In MGNLSTK-1519, we updated how STK resources are installed:

• We replaced deprecated tasks with newer InstallTextResourceTask and InstallBinaryResourceTask
• We don't strip resource extensions anymore
• We updated those resources as well, thanks to the purposely introduced ResourceCleanUpTask; this includes:
  • resources matching /templating-kit/js/*.swf
  • resources matching /templating-kit/js/*.js
  • InstallSTKResourcesTask#specialResources

Now, because google-analytics module installs its resources inside STK scriptloaders, it means the STK upgrade is taking care of them (cleanup task by JS pattern), while for fresh installs extensions are still stripped.

Worth noting that nothing is broken; just 4 minor migration diffs show up.
