Caused by {rB3e4d720ae483}.
Before above commit, this had a different path handling and
RNA_path_from_ID_to_struct() was always used [which kind of took care of
this]. Now this is only used if ptr represents an ID itself, so we are
"loosing" part of the path.
This patch adds the path back on the member_id in
wm_context_member_from_ptr() for everthing related to space_data, so
WM_context_path_resolve_property_full() can construct a full path even
for these.
