Storage Settings shift profile selection tab position

In this change, Storage Settings main UI is composed by 3 fragments.

StorageDashboardFragment only shows when there is only personal profile for
current user.

ProfileSelectStorageFragment (controls preferences above profile tab) and
StorageDashboardNoHeaderFragment (controls preferences below profile tab)
only show when current user has installed work profile.
