Bug: missing DetectorSettings reference handler

[mlinkert]

Importing files from flex/anatole/ with 4.4.0 apparently produces this error:

java.lang.RuntimeException: omero.ApiUsageException
     serverStackTrace = "ome.conditions.ApiUsageException: Missing 
reference handler for Detector:0:-1(null) --> 
omero.model.DetectorSettings:1:0(ome.model.acquisition.DetectorSettings:Hash_11575857) 
reference.
