[SFOS] Auto update results in battery drain when phone is set FlightMode

[MrWordpress84]

Dear dev team,

I identified a potential bug in meecast 1.1.15: On my Jolla C there is a problem when auto update is activated in meecast and the phone is set to FlightMode: Although all connections are closed, meecast frequently tries to establish a data connection, thereby preventing the CPUs to enter the sleeping state. This results in a massive battery drain during FlightMode. Could you please fix that issue? Other than this, I really love meecast!

Regards!
