Added troubleshooting Chrome error to installation instructions

I doubt I'm the only one encountering this issue, and that way what helped me is there already...

this isn't an x-dash specific problem, it can happen with any FT.com app, so i think maybe it should be in the wiki instead?

Mostly, I ran into this problem in this specific case, and even if the details go into the wiki (any suggestions where to put it are appreciated), I think it would be beneficial to link it from here. I have read some of the wiki when I joined but I don't recall much of it and it wouldn't necessarily be the first place I'd look for troubleshooting (because it's so large).
