[ASTERIXDB-2012][TX] Fix Sporadic double release in btree search
- user model changes: no
- storage format changes: no
- interface changes: no
details:
- LSMBTreeRangeSearchCursor sometimes unlocks twice producing
illegal state exception. This happens if:
1. the proceed call failed (causing instant lock to fail)
2. the lock was acquired and then released. This happens if:
a. the priority queue head was not coming from memory component.
b. the priority queue head was from memory component and it didn't
change when search was re-performed
3. the tuple was found to be antimatter.
- Moreover, locks that are acquired in case the mutable component is not
part of the search anymore are not released until the job completes.
