RapidPro chatbot channel - 500 from IoGT when RapidPro sends message

[sheralim012]

Currently, we are using "IntegerField" for rapidpro_message_id in the Message model, it can only hold numbers between this range -2,147,483,647 to 2,147,483,647.
An error is raised when we try to put a value outside this range.
Use "BigIntegerField" instead which has a lot more range -9223372036854775808 to +9223372036854775807. And this is the default in newer versions of Django for primary keys.

The message IDs that RapidPro sends back to IoGT are much larger than can fit in the IoGT database. The solution is to migrate the message ID field from IntegerField to BigIntegerField.
