I see what you mean about the semi-colons. Best guess is that because you downloaded closure yourself rather than pulling it in from grunt dependencies, it's a more recent version, and it has been modified to always add semi-colons (probably a good thing).

However, we don't generally check in a new version of dist/axs_testing with each commit; rather, updating this is part of our release process. So, could you please revert this file for now? You can build a local version for testing using 'grunt' (with no arguments); it will show up in gen/.
