Merge tag 'sparks-1.14.1' into develop

1.14.1
Revert "Always use env.root, else it doesn't work on local runs.", it just *really* doesn't work because env.root points to the remote path, and local django settings won't load because it's not the correct path. Sorry but we have to stay with os.getcwd() and hope the user is in the good directory on the local side. Unperfect, but doing it completely would imply creating a new env.local_root for remote tasks, which I don't wan't because it's not DRY. Perhaps I'll have a good idea in the future.

This reverts commit 56f9ec2ead24ecc46f5db3d27ab9a4264a596a7a.
