[PD-312] Removed redirect to password changing screen.

Tests pass (ran with mypartners and registration). 

Doing this prevents the case where a user is asked to change his password twice. Before this change, the flow was:

Account created by saved search -> user misses activation email so clicks forgot password -> user clicks new password link in email -> user enters new password -> user logs in -> user has to create a new password...again

Now:
Account created by saved search -> user misses activation email so clicks forgot password -> user clicks new password link in email -> user enters new password -> user logs in.

Granted, my last PR fixed the case where they missed the login password.
