Bug 26191: Relocate track_login call in Auth.pm

Bug 26191: Relocate track_login call in Auth.pm

This is a leftover from bug 22543.
Trivial move.

Test plan:
Do not apply this patch.
Pick a user that has not yet logged in today.
Only login via the opac and immediately check if borrowers.datelastseen did not change.
Apply this patch, restart, flush etc.
Only login via the opac and verify again rightaway (no further opac actions).
Now datelastseen should have been changed already.
