broken img links shown for users who don't have an email addr

[geeksville]

I think something is probably not checking that the avatar URL is valid...

[mrpollo]

we should probably add a default if theres no email present

I totally agree - the FE used to have code in there to use the placeholder gravatar if the url wasn't provided by the server (or the backend might have been doing that - I'll check later)
