Appending "-g" to yang 'uses' in referencing yang missing

ODL: Aluminium-SR0

Observation with yangs from this source:
https://gerrit.o-ran-sc.org/r/gitweb?p=sim/o1-interface.git;a=tree;f=ntsimulator/deploy/base/yang;h=b51524b568bb2aa0e48a89f4293532f5718a680e;hb=refs/heads/master

Procedure:

After mounting a netconf server exposing the yang files - the yang files are available in ./cache/schema. 

To all yang grouping statements a "-g" was appended -> ok

 To all yang uses statements which reference a yang grouping within this model were alos appended with a "-g" -> ok

However the yang uses statements using groupings from imported models are now missing the appended "-g" -> nok

Current workaround

• pre-loading of yang models to ./cache/schema
