any-of fixes

• Closes Query doesn't always initialise properly, resulting in no results returned by capture #325

Problem

In query initialization when creating predicates, the capture_id is never set for the any of predicate, leading to issues in cases where garbage data was used for the capture id, because the match would always fail then. Also, the logic for satisfying any-of predicates seems incorrect, it asserts that for all nodes, all values of the predicate must equal the node's text, which seems incorrect.

Solution

• Set the capture id in query initialization
• Have the logic of satisfies_anyof be "for all nodes, assert that any of the predicate values equal the node's text" (not all)
