Ensure partitioning wizard knows devices have been unmounted (mga#23603)

Commit 4f6b3b5 causes the isMounted flag to be set on all mounted
partitions, to ensure they are unmounted before we start partitioning.
This flag needs to be cleared when the partitions are unmounted,
otherwise the partioning wizard gets confused.
