Fix (studio-reported) issue in remapping code.

Not clearing runtime remapping data for the new ID as well as the old
one can lead to false stale data there, wichi could e.g. make indirectly
linked data be tagged as directly linked.

This would generate an error report on file write when hapening on
ShapeKey ID, since that type is not allowed to be directly linked.
