"NIEP" FDSN client not working with ObsPy1.2.2 but working with ObsPy1.2.1

Same problem as in this thread: ValueError: The current client does not have a dataselect service - #3 by LyuZinan.
It should actually not happen as much in 1.2.2 due to this change.

If this happens for more people, we might want to think about trying multiple times to discover services, maybe..
