Why:
Sometimes the latitude or longitude it passed to the map as *********
instead of the actual latitude or longitud. The asterisks are not a
string, breaking the whole array
https://github.com/consul/consul/issues/2380
What:
This commits skips invalid markers and displays the rest
How:
- Substituting the mysterious asterisks for null
(cleanInvestmentCoordinates)
- Validating the coordinates are numbers before trying to pain
them(validCoordinates)
- Adding a numeric function to validate the latitude and longitude
(isNumeric)

Until we correctly make MapLocation relation with mappables a polymorphic
one... we'll need to return the investment_id and proposal_id values.
Right now it was returning the MapLocation ID, and the JS was making a
call searching for an Investment with the MapLocation ID... sometimes
finding a record with same ID but totally NOT the one associated to the
MapLocation.
