ToDo:

• "backport" into core stable10 [stable10] Add confirm password after new password owncloud/core#34492

[sharidas]

In general I am fine with this change. But I think it would be nice if we have a ticket to add unit test for the js file, updated. Just in case every one agrees. I am fine with our acceptance test which would easily cover the code. 👍

[phil-davis]

drone CI has a js test fail. So I will look at that now...

Existing JS tests have been adjusted.

[phil-davis]

@PVince81 this is the equivalent code for the new user "set password" case to what @sharidas did in core master yesterday for the existing user "lost password" case.

It is covered by acceptance tests.

Please review and merge, or tell us if we have to try and add more unit tests.
