Description of problem:

After a user edits their username in My Settings they can't log in anymore because their password is simultaneously changed to empty string, and the login page won't allow to log in with the empty Password text box.


Version-Release number of selected component (if applicable):

tendrl-ui-1.6.3-14.el7rhgs.noarch


How reproducible:

100%


Steps to Reproduce:

1. Log in
2. Click My Settings 
3. Enter a new name in Name text box
4. Save changes
5. Log out
6. Try to log in again


Actual results:

It's impossible to log in because the password has been changed to empty string.


Expected results:

Changing user's name doesn't cause the change of password. It's possible to log in after the change of user's name with the old password.


Additional info:

The json in the POST request when a user edits their name includes 'password: ""'. It shouldn't.
