OrderEntryConfigResource has wrong supportedClass, which breaks reportingrest module

See https://talk.openmrs.org/t/cohorts-and-cohort-searches/10661/9

The problem is that OrderEntryConfigResource1_10 says it has supportedClass=Object, which means that if you call RestService.getResourceBySupportedClass(Integer.class) it returns OrderEntryConfigResource1_10. Instead we'd want that call to return null.
