Compatibility fixes for UMAPI changes
Because the UMAPI functionality around Adobe IDs is now different for migrated organizations, the client no longer does a lot of redundant validation of server-side checks. This makes it more tolerant of clients who use it against both migrated and non-migrated orgs.
NOTE: Clients that were relying on the umapi-client to default Enterprise ID country code to "UD" now need to specify it themselves.
