Fix T87189: Copy/pasting IDs does not handle properly instantiation. 

Copy/Paste uses its own code path for ID linking, which was not setting
`LIB_TAG_DOIT` for proper instantiation later on.

Would be nice the make this logic closer to the rest of the link/append
code at some point, but for now this fix will do.
