## Description
\~Only affects folders created by tests\~
Create and use helper function that sets the restore destination folders to have microsecond granularity. This is to avoid naming collisions with second granularity (of which I've observed at least once)
Switches all tests for all services/categories to use OneDrive DateTime format+microseconds
Manually verified that a manually created folder with the given timestamp format was removed by the CI purge script
