* TABL: Simplify control flow

When this commit is applied the control flow in object serializer TABL
is eased. The idoc check returns now a boolean instead of raising an exception. Main purpose is to ease debugging due to reducing the use of 
zcx_abapgit_exception%3D>raise.

* TABL: fill rv_deleted on early exit
