logictest: deflake drop_database

Previously, the drop_database logic test would list SCHEMA CHANGE GC and
SCHEMA CHANGE jobs without filtering the job description and a limit
clause, which would be non-deterministic. To address this, this patch
adds filtering on job description and removes the limit clause for a
more deterministic result.

Fixes: #148009
Release note: None
