Fix infinite refresh indicator

[flofriday]

Description

Closes: #7136

Before when refreshing any feed(s) without network the refresh indicator stayed indefinitely.

This was also the case if you were on mobile, trying to refresh a need and in the popup selected "don't update over mobile".

Notes

I am not completely sure if this is how the fix should be implemented, maybe there is a cleaner version.

Sure, thanks for the feedback.
Should I keep making issues for even relative small bug fixes? Like for now I did it because that's how it is written in the PR template that there should be a matching issue.

With the issues we want to avoid that someone spends time working on something that we later don't merge. (one example would be people updating dependencies, which needs a lot of testing - not just changing the version numbers. Another example would be adding prominent new buttons to screens to access something "in one click" - while that might help that one user, it clutters the screen for everyone else. So we need to discuss stuff like that first)

If you are working on obvious bug fixes, you don't need to create an issue :)

Makes sense, thanks :)
