#550 Suppress 'export source files' for background sessions

[Lee Worden]

I don't think this is really a meaningful operation for a background session. It's also got implementation issues: if you create a background job, then change the project by adding or removing source files, then do 'export source files' on the background directory, it'll use the current project's list of source files, not the old list that actually applies to the job.

That's true for preview as well, though that's part of the bigger issue of preview using the non-preview project description.
