Min and Max rent filter fail if there are at least 4 digits

[ludtkemorgan]

STEPS TO REPRODUCE:

1. Go to the Detroit listings page and click on the filters
2. Add at least a 4 digit number into either the Min or Max rent fields. (e.g 1000)
3. No results will appear and an error shows on the backend
   filter.1.maxRent must be a number string

This is happening most likely because the front-end adds a comma after entering it and sends that to the backend. Also it appears to have started after the Aug 1st release

QA notes: on https://detroit-public-dev.netlify.app/listings click find rentals for you now filtering by numbers bigger that 1000 will send proper value (without comma), so it will filter as expected.
Should also work for: https://detroit-public-dev.netlify.app/listings/filtered and https://detroit-public-dev.netlify.app/finder filtering
