Fix ID copying outside of Main affecting 'directly linked' status of other IDs.
Copying an ID outside of BMain should not assume that the datablocks it
uses are now directly linked. This would be wrong e.g. in case that new
no-main ID is copied from a linked data-block and is supposed to remain
a linked data.
