Title: Feature/fix frequency weighted low

Fixes Django properties for display of service frequency for low-income population served.

Also fixes division-by-zero NaN results for weighted service frequency where no matching population found within area. (The Django endpoint was returning an error to scala, saying that the value field is required.)
