When the `ms_files_rewriting` flag is enabled, `ms_upload_constants()` is required to properly set upload directory constants. Once this fires, it is impossible to clean up for a non `ms_files_rewriting` test by turning the option back off.
Excluding these tests by default offer a more consistent environment overall. Any tests written for uploaded files in multisite should ideally have a correspondign test in this area.
This commit also moves existing `ms_files_rewriting` tests for `test_switch_upload_dir()`.
