Fix redirect getting overwritten in localStorage

[JerrettDavis]

Issue #1060 refers to application's having their own internal redirect record in localStorage overwritten by the AutoLoginService. The StoragePersistenceService already handles prefixing stored values to remedy this issue. I've converted the AutoLoginService to use StoragePersistenceService instead of localStorage.

You are on fire! Thanks :-) We will look into this, a bit short of time currently, and then merge this. Thanks for your help, we really appreciate it!

We've been using the library for a bit now, so I'm always happy to lend a hand. On that note, I still need to fix the unit tests before this can be merged. I should have that done shortly.

I've updated all the necessary unit tests to make them compatible with the change away from localStorage. One minor change I implemented throughout was the inclusion of a clear method on the AbstractSecurityStorage class. This shouldn't be at all breaking, but it enables localStorage-based Unit Tests to perform post-test cleanup, if necessary. As it stands now, it shouldn't be necessary as the mock used for testing doesn't actually persist anything, but previously it was and I didn't want any sort of feature regression.

Glad to hear that you are using the lib :-) Thanks for being part of this then :) We have to test the AutoLogin Good and the Popup. @damienbod and I will run the tests and then this will land in V12. Thanks!
