v0.7.2
Try again works again after your sign-in goes stale

Fixed
- "Try again" works again after your sign-in goes stale. If a dictation could not be turned into text and you pressed Try again in History, Wispra could keep sending an old sign-in that Wispra Cloud no longer accepted, so nothing happened. Wispra now asks for a fresh sign-in by itself and sends the recording again. You do not need to sign in again.
- A busy connection no longer signs you out. If Wispra Cloud was briefly unavailable while your sign-in was being renewed, you could be signed out. Now you stay signed in and Wispra tries again later; you are only asked to sign in again when your account really needs it.
