Describe the bug
When starting a brand-new instance of VDMS and no PMGD db available. Running a query node/edge transaction (FindImage for example) will result in a query response with a ReadOnly exception error.

To Reproduce
Steps to reproduce the behavior:

1. Create a brand-new instance of VDMS
2. Perform a FindImage command with any constraints, it doesn't really matter at this point since the db is empty.
3. Your query response will contain a ReadOnly exception error.

Expected behavior
Even when the DB is empty, querying a node or edge that does not exists should result in a response with a "No entities found" message instead of an error.
