Bug 22576: OPAC password text refresh

To test:

Create a patron with a username and password
Make sure that password resets on OPAC are allowed in your system
preferences (OpacPasswordChange -> Allow)
Log into the OPAC with this patron
Click the "Change password" tab
Change the password - notice that the button to submit the changes says
"Submit Changes" and also that the success page says "Return to my
record"
Apply this patch
Reset the password again, noticing that the button to submit the new
password says "Change password" and the success page says "Return to my
account"
