Job failed due to <10 observations (but it should have about 90)

[rstudley]

A new job failed on staging. Here's the error message:

I’ve run this same test successfully before and I don’t think I made a mistake with the parameters.

Also, this might be nitpicky, but:

1. Do we need the “Calls: processJob -> getJob” part of the error message? I realize it helps you diagnose, but it does nothing for the end user. I would like to eliminate this from the message if there’s no reason to keep it in, since it makes the app look unpolished.
2. This part of the message is great: “The uploaded student list did not have a grade with at least 10 students”. But please end the sentence with a period!
