Clickatell apiMsgId parsed incorrectly for submitted SMS messages

When an SMS is submitted to Clickatell, an "apiMsgId" is returned that can be used in callbacks and status requests.

The Clickatell provider does not trim whitespace from the apiMsgId, so it is inserted into the database with leading space(s) and trailing CrLf.

This has the effect that callbacks received from Clickatell are not correctly associated with the SMS message, and are thus ignored/discarded.
