Fix to error with OLX Autoshipment Sequence Import
Autoship sequences since 5.0 can be associated with a client, but the import specification for this record type does not support client at this time. This resulted in a SQL error when attempting to import these records.
A updated version of the spec/import should be created, but for backward compatibility and to fix the error, this patch just allows the records to come in as ""no client"" or global. These can still be updated in the GUI.
