When the user is recovering the password via password reset link, after requesting the Reset Link, on the UI they got "Your password was sent to the provided email address."

Steps to reproduce

1- startup vanilla 7.1 patched with dxp-2
2- set "Allow users to request password reset links"  in "Control Panel/Configuration/Instance Settings/Authentication" and uncheck the other options in that block (starting with "Allow...").
3- create a testuser, login with it & logout
4- click 'Forgot Password' in Login portlet from another browser
5- provide testuser's credentials (email, captcha, security answer) 
6- click 'Send Password Reset Link'

Expected UI message: "An email has been sent to the provided email address" (something that works well with both 'password reset link' and direct 'reset password' request)
Actual message: "Your password was sent to the provided email address."

Reproduced on:
 7.1 dxp-2
 7.1.x @ 09ac7a44391d5ee940b993b435f5f433378309db
