When changing watched literals of a rule, update the parent's next pointer

Browse source 
The previous rule was not previously updated to point to the next rule when
removing a middle rule from the watch tree for a literal. This resulted in
jumping from one literal's watch tree to another's, which could then jump
back to the original and cause infinite loop in a case like #265.

Fixes #265
