ADT Manifest Editor: Fix for uses-sdk dup that won't go away.

Browse Source 
It was a display issue only, meaning the actual XML node was
being deleted but the Ui model was not updated properly. The
actual cause is that this is a mandatory node, and mandatory
nodes must stay as "fake nodes" in the Ui model. However
only one such node needs to stay in the hierarchy.

SDK BUG 2147112
