On the update page »Update was successful …« also show spinner for feedback

[jancborchardt]

When the update was successful, first the spinner and all the info shows. Then when it’s finished, a checkmark appears and it says »redirecting you to Nextcloud now«. But there’s no real loading feedback.

It’s a bit tricky/strange but next to the checkmark there should also be a loading spinner. Or next to the redirect message. Because currently there’s 3–5 seconds where you don’t really notice if something happens.

@jancborchardt
Could not see the icon-checkmark-white but made it so the loading circle is still there to send feedback that the redirect is in progress.

Changed the text a bit

Second option above, which should I commit and how to handle new strings in the language packs?
