Resolve "Admin > New user form > Error state > Inputs misaligned"

What does this MR do?

Fixes input alignment problem in user admin form when a validation error occurs.

Explanation

Rails wraps each invalid input + label in a <div class="form-errors">. This leads to incorrect columns alignment. With this fix we wrap the label in a <div class="col-sm-2 text-right">.

Are there points in the code the reviewer needs to double check?
