Not used file disappears when I cancel relinking process

[Sven Brencher]

If I use the new Replace Media function on a file that is not used in the sequence the file is removed from the Files Panel if I just cancel the dialog without relinking to another file.

Thanks, Sven.  I'm able to reproduce this quite easily.  I'll make sure a bug is submitted to the team.
