Fix T90840: Can't duplicate or copy (Ctrl-C) object from linked file.

We need to separate the flag telling duplicate code to not handle
remapping to new IDs etc., from the one telling the code that we are
currently duplicating a 'root' ID (i.e. not a dependency of another
duplicated ID).

This whole duplicate code/logic is still fairly unsatisfying, think it
will need further refactor, or maybe even re-design, at some point...
