Re: #973
Jinja2 added _elif, compress inside an elif tag getting missed in offline compression.

Not super familiar with writing tests, feel free to change it as you see fit.

Thanks! how did you run the tests? specifically, it's rather important that you have requirements/tests.txt installed and use compressor/test_settings.py as settings. also, please verify that the output files (which are pointed at by the new script tags) contain what you expect.

also, your PR contains some old commits. That doesn't matter much though, we can just squash-merge the PR so those will be gone.

I'm unfamiliar with writing tests or contributing to django-compressor specifically, so not sure what actually needs to be done here. I am not interested in figuring out how to create a viable pull request to fix this issue. I've forked and fixed this for my needs. It is a bug that needs to be fixed, and it's a fairly simple fix, so if the contributors to this package feel it worthwhile you're welcome to sort out the tests.

for the protocol, the change seems correct, but the newly added tests are failing. if anyone wanto to pick this up, you'd need to debug the test and verify that the rendered output of _render_script and _render_result in _test_offline look good, and then adjust the hashes.
