The root of the problem was that findMainViewFileID(File, Function) could return some ID for any given file,
even though that file was not the main for that function.
This patch ensures that the result of this function is conformed with the result of findMainViewFileID(Function).

Please note, that this patch is based on http://reviews.llvm.org/D18758.
