Deleted function group is still serialized as empty XML

[pokrakam]

A TADIR entry exists for a deleted Function Group, the exists method fails, yet an empty XML file is generated containing

<?xml version="1.0" encoding="utf-8"?>
<abapGit version="v1.0.0" serializer="LCL_OBJECT_FUGR" serializer_version="v1.0.0">
 <asx:abap version="1.0" xmlns:asx="http://www.sap.com/abapxml"/>
</abapGit>

I manually created a tadir entry for a function group but I'm not able to reproduce this. It seems also very unlikely that anything is serialized if exists fails:

abapGit/src/objects/zcl_abapgit_object_fugr.clas.abap

Lines 1375 to 1379 in fd673da

	IF zif_abapgit_object~exists( ) = abap_false.
	RETURN.
	ENDIF.
	serialize_xml( io_xml ).

Aware of this, yet it was happening on a customer system. I've got it on my todo to debug when I'm next working on that system to see what's going on.
