Title: UP-4056 Remove attempting password retrieval multiple times

https://issues.jasig.org/browse/UP-4056

Found out that if PGT was not in cache before PasswordCachingCasAssertionSecurityContext is invoked, retrying multiple times won't matter because assertion won't contain the PGT. Removing extraneous code to avoid confusion.
