 Updating a plugin on the `plugin-install.php` screen uses an ajax process
 to update plugins in-line. When a plugin upgrade succeeds, the button is
 updated accordingly; however the click handler for the button is still in
 place, and clicking the button again results in some unexpected behavior -
 the upgrade request fires again and fails, and the complete checkmark
 spins around:

 To fix this, we should prevent the action for disabled buttons, patch
 incoming.
