The `LibraryInstallerTest::testUninstall()` method mocks a `Package` object, but did not set an expectation for a call to `getName()`, while that method _is_ called in the `LibraryInstaller::uninstall()` method.
Without expectation, the mock returns `null`, which was subsequently being passed on to `strpos()` leading to the below error.
Fixes:
```
Deprecation triggered by Composer\Test\Installer\LibraryInstallerTest::testUninstall:

Not all tests in the `InstallerTest` class actually create a temporary directory and set the `$this->tempComposerHome` property.
Those tests which didn't, throw a notice in PHP 8.1.
Fixes 3 notices along the lines of:
```
Deprecation triggered by Composer\Test\InstallerTest::tearDown:
is_dir(): Passing null to parameter #1 ($filename) of type string is deprecated
Stack trace:

1 tests/Composer/Test/InstallerTest.php(53): is_dir(NULL)
...
```
... to proof the existence of the bug and demonstrate the effect.
Note: in the test the backtrack limit is being lowered (and restored back to the default afterwards) to prevent the tests needing ridiculously huge test fixture files.
* PHP 8.1/Tests: fix some deprecation warnings
The default value for the `preg_split()` `$limit` parameter is `-1`, not `null`.
Fixes numerous `preg_split(): Passing null to parameter #3 ($limit) of type int is deprecated` notices when running the test suite.

* PHP 8.1: fix deprecation warnings / http_build_query()
This fixes all relevant calls to the PHP native `http_build_query()` function.
The second parameter of which is the _optional_ `$numeric_prefix` parameter which expects a `string`.
A parameter being optional, however, does not automatically make it nullable.
As of PHP 8.1, passing `null` to a non-nullable PHP native function will generate a deprecation notice.
In this case, these function calls yielded a `http_build_query(): Passing null to parameter #2 ($numeric_prefix) of type string is deprecated` notice.
Changing the `null` to an empty string fixes this without BC-break.
Fixes a few deprecation warnings found when running the tests.

* PHP 8.1: fix deprecation notices / PharData::__construct()
This fixes all relevant calls to the PHP native `PharData::__construct()` method.
The second parameter of this method is the _optional_ `$flags` parameter which expects an `int` of flags to be passed to the `Phar` parent class `RecursiveDirectoryIterator`.
Fixed by passing the default value for the `$flags` parameter as per the `RecursiveDirectoryIterator::__construct()` method.
The third parameter of the method is the _optional_ `$alias` parameter which expects an `string`.
Fixed by passing an empty string.
Fixes various notices along the lines of:
```

This adds support for Xdebug3 modes and changes the default behaviour
from always restarting if Xdebug is loaded, to only restarting if Xdebug
is active.
Xdebug is considered active if it is loaded, and for Xdebug3, if it is
running in a mode other than `xdebug.mode=off`.
