Avoid creation of duplicated verifications dictionaries when you do
the next sequence:
 1. Creates an object to verify (i.e. the "+5555555" phone number)
 2. Verify this mobile.
 3. Removes this mobile.
 4. Creates again the same object (again "+5555555" phone).

This sequence duplicated the verification item. Now is fixed.
Some usability improvements in the actions and verification popup:
 * When some action is triggered, the active tab content will be
refreshed.
 * The verification code popup will focus in the input field.
