Fixing errors with registration page

- Couldn't select a logo on Firefox, as the touch-swipe blocks the
  `mouseup` event needed for `click` to work
- Issues showing an error with the password when team names are present
  - The lack of an error text block caused JS errors
  - The password field would not be marked in red
    - `$('.el--text')[1]` would refer to the first email field,
      rather than the password field
