Merge lp:~adeuring/charmworld/1192559-forgotten-jenkins-results into lp:~juju-jitsu/charmworld/trunk

[Abel Deuring]

do not drop old charm test results when the Jenkins server can't be reached.

This branch has a trivial fix of an error of the ingest worker:

charm['tests'] and charm['test_results] are set to an empty dictionary in update_jenkins_data(); when store_provider_results() (called by update_jenkins_data()) raises an exception, no test data is added for the current provider. This may result in completely missing test data. The fix is obvious, I think.
