en_energy_setpoint is not findable in current spiral scans. @EliotGann thinks this is a result of changes to the energy PV.
This causes loads to fail because it gets set to None and then calculation of wavelength from energy fails.
Two needs:
1) If energy is None, wavelength should just be None, not error.
2) SST1RSoXSDB should support loading from a backup source for metadata, e.g. en_monoen_readback, as a fallback.
