chore(css): removing instances of transit lib

I give the green light. r+, thanks @pdehaan!
fix(tests): Ensure all tests pass.

* Add front end tests for confirm_reset_password to ensure coverage.
* Update Selenium tests to ensure localStorage and sessionStorage state is cleared for the settings tests.
* In the selenium tests, use safeEval when clearing localStorage to ensure operation completes before continuing (this is what WD does too).
