Refine `view_dependencies` query to return user-conrolled objects

[whit0694]

Closes #18

As mentioned in https://github.com/cdinger/scenic-oracle_adapter/issues/18#issuecomment-2206657472 this updates the query so that it only returns a dependency if it exists in user_objects. So dependencies such as user_scheduler_jobs or other Oracle-controlled objects are excluded.

This should be done. Just waiting for tests to run, then I'll rebase.

https://github.com/cdinger/scenic-oracle_adapter/pull/19/commits/c75af155431604a53a87eef8e708c1e6701d276f sneaks in one more minor tweak. Like I said, it's a weird edge case. But it's definitely one we have!

Tests pass.
