merge-recursive: fix verbose output for multiple base trees

Browse Source 
One of the indirect callers of make_virtual_commit() passes the result of
oid_to_hex() as the name, i.e. a pointer to a static buffer.  Since the
function uses that string pointer directly in building a struct
merge_remote_desc, multiple entries can end up sharing the same name
inadvertently.

Fix that by calling set_merge_remote_desc(), which creates a copy of the
string, instead of building the struct by hand.
