Formatting errors per adapter

[dballona]

Some adapters may accept different characters as the phone to receive message.

We should create error specializations (or maybe just log errors?) for each one of the Adapter classes, with correct messages if something goes wrong, e.g.:

Twilio:
21211: Invalid 'To' Phone Number
21401: Invalid Phone Number
21407: This Phone Number type does not support SMS
21614: 'To' number is not a valid mobile number
