Fix bug where sending messages failed

When building the template it was looking for a placeholder called
((phone number)). This caused it to fail because the template it had did not
match the personalisation it was being given.

`Template` has an optional parameter for specifying personalisation values that
should be ignored. The recipient of a message is an example of such a value.

This commit passes that extra parameter, which fixes that bug.
