Avoid returning HttpServerError for things not server errors

With the new django, alerts are raised for everything with status 500,
not juse exceptions. This put a light on a number of places where we
were returning 500 server error code for things that are not actually
server errors. Some should be a regular 200 ok with an error message,
and others should be a permissions error.
