Fix bit vector tests (#110521) (#110525)

Bit vector tests were failing in cases where an index has more than 1 shards.
For error cases when we expected a failure of the whole request, shards
with empty documents returned success and the whoel request unexpectedly returned 200.

Ensuring that index contains only 1 shard fixes these failures.

Closes #110290, #110291
