[Bug]: Refresh Failed toast often seen when reopening app from minimised

[catch-21]

Describe the bug

When I reopen the app from minimised state I often see 'Refresh Failed' 'An error occurred and couldn't refresh the wallet. Please try again.' toast message. A manual refresh will work and there appears to be no connection issue. We should only show this toast when there is a legitimate problem.

Reproduce

1. Close Bitkit to minimised state
2. Wait a short while (2-5 minutes)
3. Reopen Bitkit from minimsed state
4. Observe 'Refresh Failed' error toast
5. Perform manual refresh and confirm there is no problem with refreshing
