Handle LIMU <-> R3TR conversion in transport checks

[fabianlupa]

Going from top to bottom the first error is that the transport only contains the LIMU REPS object ZAAAGIT_TEST, while the check expects R3TR PROG ZAAAGIT_TEST.

I would have expected that the first creation of an object uses the "full" object in the transport with R3TR and only subsequent transports use the subobjects with LIMU.

Easiest fix would probably be to just convert every LIMU object to its R3TR parent before comparing with abapGit items.
