#Install: Update app on new release, app freezing just displaying runbox logo

[castaway]

Describe the bug
Sometimes the runbox7 application freezes, just displaying the Runbox Logo mid screen and nothing else

To Reproduce
Steps to reproduce the behavior:

1. Keep an open tab with runbox7
2. Wait .. return to it after an application update
3. Refresh the browser, may only have the logo on white screen

Expected behavior
App to display the dialog which prompts the user to update the application

Screenshots

Desktop (please complete the following information):

• OS: Linux
• Browser Vivaldi
• Version 7

Additional context

If we stop the code in devtools:
ngsw-worker stops with an uncaught error in cacheBustedFetchFromNetwork, throw new SwCriticalError(Hash mismatch (cacheBustedFetchFromNetwork): ${req.url}: expected ${canonicalHash}, got ${cacheBustedHash} (after cache busting)); Which appears to mean that the calculated hash of the fetched code does not match the hash in nsgw.json

Can we (at least initially) catch the thrown error (in updatealerts.service.ts?) and force a refresh?
