i started out with a plan to test out this PR in all 4 possible scenarios - multi-facility user in a facility with 1 class, multi-facility user in a facility with more than 1 class, single facility user with 1 class, and single facility user with more than 1 class. i ended up experiencing an issue with the 1st & 2nd scenarios, so decided to pause my testing there for now.

in the case of a multi-facility user with any number of classes, choosing "New Lesson" seems to always send the user back to the "All Facilities" page instead of to lesson creation. i think this may just be an issue of adjusting the conditions in which the navigation guard is called for this route or the information that the guard is provided.

cc @rtibbles as he may have some insight!
