Bugfix: Uninstall-PSResource should delete subdirectories without Access Denied error on OneDrive

[anamnavi]

Currently, when uninstalling a module that was installed to a OneDrive module path, it deletes the module files successfully but not the subdirectories and an error is thrown. The subdirectories need to also have their file attribute set to FileAttributes.Normal to allow for deletion.

Tested manually on PS7.
