All callers of fill_tree_descriptor() have been converted to object_id
already, so convert that function as well. As a nice side-effect we get
rid of NULL checks in tree-diff.c, as fill_tree_descriptor() already
does them for us.

Changes from v1: Don't mention sha1 in documentation anymore, #undef
ENTRY_OID. Thanks for spotting, Johannes!
