Catch crash in mobile network ProgressDialog

When enabling "Automatically select network" in "Settings -> Network &
internet -> Mobile network -> Advanced" and rotating the device while
the dialog is showing there will be an IllegalArgumentException since
the decorView isn't attached to the window when dismissing the dialog.
Fixed by simply catching the exception since the dialog will be gone
anyway.
