Allow a Sync user to undo an incorrectly registered email address

[ryanfeeley]

So that I can avoid a world of manual undo pain, as a registering Sync user, I want to be able to go back on the Confirm your account screen which will clear the email address seeded into my Firefox desktop client.

@ryanfeeley why is this sync specific? why not in general for FXA?

Actually great idea for all of them. How the unverified email address gets unstuck from the desktop client software is harder than just the web, but yeah, let's support this feature for web and native clients.

@ryanfeeley - I have always wanted the back button, I'm surprised there isn't a bug on file about it. If the user goes "back", perhaps we should remove the just registered email from the dB. We have to make sure Sync can handle the user registering a new email w/o verifying the old one.

Desktop will be capable of handling this fine - probably with a trivial change so desktop can listen for a "forget the current (unverified/incorrectly-typed) user" command.

Thanks for the quick confirmation @mhammond.

Sort of a dup of #2002

@ryanfeeley - @vladikoff is right, I'm closing this one as a dup of #2002
