The app crashes while looking for an update

[kingalg]

Version: 4.0.0-alpha.4 (happened in 4.0.0-alpha.3 as well)
System: Linux (I only caught it on Linux but it's not impossible that it can also happen on other desktops)

The application crashes while looking for an update - it happens when the app is already on the newest version and there is no more updates.

Steps to reproduce:

1. Have a fully updated Quiet on Linux and use it as normal. At some point you may get a popup with js error.
   It doesn't happen every time, but it happened to me a few times already.

I'm attaching print screen of error and logs. The last thing in logs before the app crashes is:
"Update installer has already been triggered. Quitting application."
