TimedMediaHandler now fetches the getid3 library via composer, and requires that composer be run after git clone. This doesn't appear to be happening when installing the 'timedmediahandler' role and running a 'vagrant provision'.

Result is that an upload of a WebM or Ogg file kicks back a 'Class not found: getid3' error.

Workaround: manually run 'vagrant git-update' after provisioning.
