geocoded_by address method not called on updating any field

[jaswinder97]

Expected behavior

It should update lat lng on updating any field change in geocoded_by address but only called on create callback of activerecord

Actual behavior

It doesn't geocode on activerecord update callbacks

Steps to reproduce

• Declare model declarations as:

   class Location < ApplicationRecord
     ...
     # Geocoding
     geocoded_by :full_address, lookup: :google
     before_save :geocode

     def full_address
       [line_1, line_2, postcode, city, country].reject(&:blank?).join(', ')
     end
   end 

• try updating any field in full_address like line_1 or line_2 or postcode of location.

Environment info

• Geocoder version: geocoder (1.5.1)
• Rails version: 'rails', '~> 5.0.3'
• Database (if applicable): postgresql
• Lookup (if applicable):

I reproduce the bug, do you have found a solution please ?

This is difficult to debug without more information (I can't reproduce it). If the before_save callback is only being executed on object create, that's a Rails or application error, not a Geocoder bug.
