Add data to NoMethodError for progress

[maureensturgeon]

We've had an error on /dashboardapi/section_level_progress/<section> which has been increasing in frequency over the last few months:

The error is NoMethodError: undefined method []=' for nil:NilClass, which I determined would be caused for a bubble choice level if a student does not have overall progress for the level but has progress on a sublevel. It's hard for me to imagine how this could happen. I reloaded the endpoint with the same parameters that it failed with and got 200s. I logged in as various teachers looking for a pattern that could be causing this among their student progress with no luck.

I need more data. So I've rescued the error and re-raised it with more information about the specific student and level.

Testing story

I've tested locally that raising the error results in the expected message:

Follow-up work

Once I have more data, I'll look into the specific levels and students that this is happening for.
