Selecting "Try Finding Your Username Again" from the USS screens does not work

Bug description

_Minor issue, but in testing out the USS flows it appears that th_e "Try Finding Your Username Again" link in the forgot username password flow does not take you anywhere.

The same is true for the Try Resetting Your Password Again link in the forgotten password flow. 

How to reproduce the issue

1. Install AM
2. Configure User Self Service with defaults - (Configure -> Global Services -> User Self Service - you can use the selfserviceenctest and selfservicesigntest key aliases here)
3. Enable "Forgotten Password" and/or "Forgotten Username" service in the configuration - also disable the "email verification" option to prevent the need to verify email here when testing this locally etc.
4. Logout.
5. On the login page select "Forgot Username?"/"Forgot Password?" and enter some invalid values 
6. On the resulting page you should be displayed with a link to "Try Finding Your Username Again" - click this.

Expected behaviour

Be taken to the start of the forgot username/password flow

Current behaviour

User remains on the same page displaying error

Work around

Simply click the "Return to Login Page" to return to the login page and have the option to click the "Forgot Username?" or "Forgot Password?" links to start the flows again.

Given this workaround - would it perhaps make sense to simply remove the "Try Finding Your Username Again" links from these pages?
