[FDS-2502] Walk back up directory tree to get location in project

[BryanFauble]

Problem:

1. When a nested file is used as the datasetId the walk function was only returning back the path where the nested file was located and below. It did not consider where it was in the project if it was in a nested folder.

Solution:

1. Walk back up the directory tree until we get back to the project, this was we know the prefix of where we started the walk function and can return back the correct location.

Testing:

1. There is at least 2 integration tests covering this.

🔥 LGTM! Not sure if we just wanted to add the test in that branch as well, but going to pre-approve.

@BryanFauble I think one of the tests failed.
