Delay sign in notification

[cstiens]

Delay ‘signing in notification’ 5 seconds so it doesn’t show every time the user logs in.

@n8fr8 We've discussed this before. Is there any reason not to delay showing the signing in toast?

with the fix related to persisting the background connection, I think this is not much of an issue anymore. We really won't see the "signing in" unless it is actually disconnected now.
