[TECH DEBT]: Integration tests needed for `scan-tables-in-mounts-experimental` & `migrate-tables-in-mounts-experimental`

[asnare]

Current Behavior

We have integration tests that cover most workflows to ensure that they run. Currently we are missing integration tests for some workflows:

• scan-tables-in-mounts-experimental
• migrate-tables-in-mounts-experimental

Expected Behavior

These workflows should also be covered by integration tests.

@gueniai : I am inclined to close this as a "won't fix" given those workflows are experimental and (I think) legacy. Could you make the final call?
