Fixes 3 things I notices with the install service:
The CleanUpEFTDirectory didn't actually work properly for a fresh install as it was relying on the stored EFT version rather than the target location we were trying to install to.
Progress for the download would get reported as 1 at the end when it should be 100.
Removed the call to CopyEftSettings as we already do that elsewhere if the user requested it.
