Bug/3899/upload same map twice

[BenediktMehl]

App freeze when uploading a file that is already loaded

Closes: #3899

Description

When uploading, if all files are already uploaded, the application remains stuck in the loading animation. The visibleFiles does not change if only already uploaded files are uploaded again (This behavior was introduced in #3788). This was intentional, but it had the side effect that the RgNx store did not trigger the effects that would normally follow a file upload. One of these effects was responsible for removing the loading animation.

I fixed the issue by checking if a file upload added any new files. If no new files were added, there is an error that is caught by the file upload process, which then stops the loading animation.
