When saving a timeline project after opening - it puts wrong default filename in dialog box

[dheista]

Steps to reproduce:

1. Open LSG
2. Load a timeline project (ie: shine.igp) in a specific location
3. Edit it, and add or change something.
4. Go to File -> Save project

Instead of seeing shine.igp in the dialog box, it shows example1632 and it's default location is a different location than the original file was loaded (in my case - it was in ../LSG/ directory so I have to navigate to that directory, and then click on the greyed out shine.igp file and hit save, which then brings up the "are you sure you want to replace..." dialog box.

At the least - it shouldn't change filename or location.
