Currently, being able to create a lesson without resources is by design because lessons use an 'auto-save' functionality. This is different from quizzes which has an explicit 'save' step. We may revisit this in the future, but that's a separate issue. (cc @khangmach @jtamiace)

However, there are two things we should do:

1. make sure that empty lessons don't show up for learners
2. either hide empty lessons from reports entirely, or make them show up as 'not started' rather than 'completed'

We can also disable the 'change' link on the lesson details page, then re-enable it when they have at least one resource

Still extant on beta9.

@radinamatic The patch that should hopefully fix this is still open. You can test it by pulling #5140
