Loading a staged user can result in a UUID username

[Jeff Godin]

When loading a staged user in the user editor, if the staged user's username is a UUID, the form field is set to that UUID value. It is unlikely that we would ever want to actually create a user with a UUID value for a username.

When creating the user, staff currently need to take manual steps to remove the UUID value and replace it with either a barcode by default or some other manual value.

This is partially mitigated by the following commit related to bug 1207396, which allows staged users to have a non-UUID username:
* 4a3a719 - LP1207396 user stage allows username selection

It would be good to eliminate the UUID altogether, falling back to the staged barcode (if there is a staged card) or a blank value which will populate when staff enter a barcode.

This will bring some consistency to the user creation process, whether the patron is new, cloned, or staged.

Working branch to follow.
