Trusted locations edit path should work for subdirectories

[reddyashish]

Purpose

Task: https://jira.autodesk.com/browse/DYN-5090

When a trusted path is edited to its subdirectory, it should update to the subdirectory path. Since the subdirectory was already considered a trusted location, it was not being updated previously.
For the add path button, a subdirectory of a trusted location should not be added as a new path as the parent directory is already added.

Updated the edit icons.

I noticed that in this PR we did not delete the folder icon which is no longer used. Can you confirm and add a follow up PR deleting them?
