"replace clip" does not work if the new clip has the same filename but is in a different directory

[Alistair Buxton]

Suppose you have a jpeg image with the titles for your project. You might call it:

~/Project/Season1/titles.jpg

For season 2 you make a new title:

~/Project/Season2/titles.jpg

So, to reproduce this bug:

1. Make new project.
2. Import ~/Project/Season1/titles.jpg and drop it on the timeline.
3. Right click it on the timeline and chose "replace".
4. Select ~/Project/Season2/titles.jpg to replace it.

The image is NOT replaced - the old image remains instead.
