When using PLUGINS_COMMIT stalls in run-worker.sh

[ErinWeisbart]

With git checkout ${PLUGINS_COMMIT} || echo "No such commit, branch, or version; failing here." & exit 1
Doesn't return error message but it stalls forever (presumably because it's triggering exit)

With git checkout ${PLUGINS_COMMIT} || echo "No such commit, branch, or version; failing here." && exit 1
Returns more information but is still presumably triggering exit as it stalls forever after checkout.

With git checkout ${PLUGINS_COMMIT} || echo "No such commit, branch, or version; failing here." it proceeds.
