Fixed the failing test:

./dotest.py -A x86_64 -C clang -v -t  -f TestImageListMultiArchitecture.test_image_list_shows_multiple_architectures

The problem was that if the platform wasn't compatible with the current file in the "target create" command, it wasn't finding a platform that was like it used to.

Also, the currently selected platform was being used upload the file _before_ the target was created which was incorrect as "target create a.out" might switch platforms if its architecture doesn't match, so I moved the uploading to happen after the target was created so we use the right platform (the one in the target, not the selected one).
