Fix in cleanup code (exitApplication)

There are some scenarios where a single process executes GeneXus objects which end up with IsMain being true
For example, some GXTest/GXFlow code instantiates procedures without passing them a GxContext.
This was making the coverage trace file to try a premature cleanup and the need to start another coverage session
