The type of the ``path`` value changed in #38188.
This updates the type in the unit test, as well as rearranges some
of the imports to be more standardized with ``ensure_in_syspath``.
* Hash fileclients by opts
There was an issue whereby the cache of the fileclient was being overwritten
by dueling minion instances in multimaster mode. This protects them by hashing
by the id of opts.
Closes#25040
* Silly typo!
* Remove tests which do not test any actual functionality or are too tightly coupled to the implementation
