I have been thinking a fair amount about the part of this patch that I'm the least sure about: the part in components/fxa-client/src/state_machine/mod.rs where we avoid calling on_auth_issues() on the Uninitialized -> AuthIssues transition. When I wrote it, I felt reasonably sure that this change wouldn't have any negative effects because that state transition should only happen after we already transitioned to AuthIssues and because the effects of on_auth_issues should persist through the next initialization. But having thought about it a bit more, I believe that there are ways of having the Uninitialized -> AuthIssues transition without having previously been in the AuthIssues state. So I think I may have to undo that change. But I'm not sure of the correct way to address the issue that it always runs on_auth_issues when we start up in the AuthIssues state, resetting the last_auth_recheck_time timer. I'm going to have to think about this.

I ended up not putting the logic to reset the auth timer in on_auth_issues() because of the issue I discussed above. To summarize, we always call on_auth_issues() on the Uninitialized to AuthIssues transition which causes the recheck to never happen since we never see an expired timer. But this means that I've basically littered the transition() function with account.reset_auth_recheck_timer() calls. Which doesn't feel great since it makes maintenance of this function kinda nasty. I'm not sure what a better option is but I'm open to ideas.
