shellMountDialog: Check for changes before creating new buttons

Browse Source 
When updating the buttons of the mount dialogs, compare the new buttons
to the old ones and only create new buttons in case something changed.
This makes sure key focus isn't reset or lost unnecessarily while a
dialog is opened.
