Handle scripts that don't expose any variables

[MarcusNoble]

Currently the webapp is unable to trigger a reduction job if the reduction file doesn't expose any variables.

This needs changing to make it easier to get people on board with the system so autoreduction can be performed before any instrument scientist has needed to modify the script.

For Tester:

1. SSH onto datareducedev.isis.cclrc.ac.uk
2. cd /var/www/autoreduce_webapp
3. python /var/www/autoreduce_webapp/manage.py test autoreduce_webapp.tests.QueueProcessorTestCase
4. Verify all tests pass

Hi,
