Use predictable order to list available users

[SamuelWei]

What does this PR do?

The list of available users is now sorted by name, resulting on the fixed order if the user list doesn't change.

The previous implementation resulted in a flickering user list, that should be fixed with this issue.

I believe the hook useUsersBasicInfo should be used here, and the query should include an order_by clause from the start.
That way, we can prevent unnecessary updates.
With your patch, the sorting fixes the bug visually, but the component will still receive updates and trigger network traffic just because the database changes the order (even if the data itself hasn’t changed).
