Lots of SVG source files broken since svgo optimization

When wanting to edit some icons, I stumbled upon this issue:

This seems to be caused by the SVGO optimization: #1534

While they seem to be correctly displayed, Inkscape has big problems showing them correctly. There’s a reason we use Scour as per https://github.com/nextcloud/server/blob/master/core/img/image-optimization.sh#L10 and not SVGO. ;)

cc @skjnldsv could you check it out? In doubt I’d say your PR needs to be reverted and we should do it via Scour instead – which was already used on most of the icons.

@pixelipo while you’re at optimizing, maybe you can look into reverting #1534 and recompressing the icons using Scour instead (which is not as lossy as SVGO apparently). cc @skjnldsv

@jancborchardt sure, I'll take a look at it. Assigning myself on this if you don't mind, @skjnldsv
