I'm seeing the setup screen appear in Fennec, even though I have no previous profile on my device. There's two places I see us doing work we don't need. First, my brilliant GeckoDirProvider is creating a profile for us, even if we don't have or need one, which means we always think we have a profile. Secondly, I'm seeing a lot of time spent in ensureSqliteLibsLoaded even though we aren't doing a migration. We'll do this on every startup, so we should delay and only do it if we know there's a data to migrate. Patch for the second coming. I avoided offering the first option earlier because its a little tricky I think...
This cuts the migration time from 500-100ms to around 3ms for me (to be fair I only saw 500 once). I assume we're hitting it every time, which is why I constantly see the startup splash fly by for a second I assume.

Dang it wrong patch. One sec...
I moved these timers outside the getProfileDir loop so that we could also include it in our measured time here (although its very small for me...).
