App updates cause the VPN to silently disconnect

[dholbert]

STR:
(1) Wait until the Play Store shows that you've got an update available for Firefox VPN. (Don't update yet, though)

(2) Open the Firefox VPN app and connect.

(3) Switch to Google Play Store, and accept the Firefox VPN app update.

ACTUAL RESULTS:
Firefox VPN silently disconnects (and its icon in your Android tray disappears). It don't get any notification or warning that I'm unprotected.

EXPECTED RESULTS:
Not sure what's feasible, but we should avoid silently disconnecting, if at all possible. e.g. perhaps (if doable):

• reestablish the VPN connection automatically so the user is only in a not-protected state briefly
• or show some messaging to let the user know that an update was just installed & they might need to reconnect
• or maybe we should just prevent automatic updates (of our own app) while the VPN is connected
• or maybe something else (again, no idea what's possible)
