Fix (studio-reported) bad remapping of libraries.

New remapper code would also fail in some cases when remapping
libraries, similar to the issue yesterday, because ID_LI type had no
mask value.

That would fail to remap `parent` member of a library to NULL when
deleting that parent, leading to a crash e.g. in Outliner tree building
code.
