Refs #14025. Fixed a bug deep in reduction gui framework.

Property method instrument_name and facility_name returned False if
instrument_name or facilty_name had been set up and True if they
haven't.  It does not seem right and by then there is no way to get
correct facility and instrument name from this class.
