Fix: Add conditional to not lock empty list of resources (#1760)

### Feature or Bugfix
- Bugfix

### Detail
In #1706 all the scenarios
tested had multiple Datasets sharing a shared-Glue database. The issue
is that when there is no common shared Glue database the lock will try
to lock an empty list of resources, resulting in timeouts in
`backend/dataall/modules/s3_datasets_shares/services/share_processors/glue_table_share_processor.py:248`
