Added tests for global state stealing

Browse Source 
State stealing is a tricky part of managing the xored-globals. When
removing a metadata-pair from the metadata chain, whichever
metadata-pair does the removing is also responsible for stealing the
removed metadata-pair's global delta and incorporating it into it's own
global delta. Otherwise the global state would become corrupted.
