Make gmail adaptor attachment optional

[martalovescoffee]

Hey all. Is it possible that attachments is required to send emails using the gmail adaptor? (And if so, can we make that optional? It's optional when sending via the Gmail UI!)

Yes, this should totally be optional.

Is this blocking anything? It's probably a really easy fix

Not a blocker currently. Taylor rised it up, so will try to include in the upcoming sprint.
