Audit fixes

Several changes to get past some of the hurdles on Audit; not finished, but had to pause it to work on adapting for GAPI.  They are (in commit order):

- Made audit setup file findable through relative path.
- Corrected selector for `+ Audit` button
- Made it look at different setup files depending on the test
- Change input method for dates to click on calendar instead.
- Compare audit contact to test user instead of same user string every time.
- Corrected selector for newly-created Audits
