Change password logout

[lmmrssa]

When trying to change password if we put wrong password as old password you get logged out. You will notice this once you try to navigate to another page.

Will require research into https://docs.couchdb.org to see if there is a way to check user credentials without a request to the _session endpoint.

Also applies to other dialogs where the password is checked (sync, upgrade, etc)
