Error sending via gmail to invalid email address

[mhammond]

Found in production logs and reproduced here. Attempt to share a link to an address "foo.bar", which is obviously invalid. F1 displays the "goofed up" message with the following in the logs:

14:30:20,595 ERROR [linkdrop.lib.helpers] [worker 2] ((,), {}) failed

Looking through the logs, many people hit this bug when they attempt to enter a person's name in the "to" address - I guess auto-complete isn't working for them and they assume f1 will match names with contacts behind the scenes?
