Add language icon to team stream

[bradhvr]

I added the language icon to the top right of the team stream solutions, per issue #3020.

Coverage remained the same at 82.667% when pulling 0bde320 on bhoover85:add_languange_icon_to_team_stream into 8bbe89d on exercism:master.

Great ❤️ Can you add before/after screenshots to this PR please.
(I know you've done some in the linked issue but it makes evaluating the PR easier if the changes are clearly visible here when reviewing.)

[bradhvr]

Sure, here you go...

Before

After

[Insti]

Will this also cause the icon to appear on regular language streams?
In which case all the language icons will be the same.

(It's probably fine if it does, but it would be nice to have the consideration documented and maybe add a screenshot of that case too.)

[bradhvr]

You mean if someone filters by one of the languages? Yes it will appear on those as well.

[Insti]

Also on the regular language tracks that aren't part of a team stream, for example: http://exercism.io/tracks/ruby/exercises

[bradhvr]

Oh I see... yes it does.

[radar]

Is it possible to get some alt-text for this icon too?

[Insti]

@radar that will require changing the track_icon view helper and probably belongs in a different PR, will you create a new issue for it please?

I merged it manually in 0de777d

[kytrinyx]

Thank you so much @bradhvr!

@kytrinyx, I think my CSS change may inadvertently have gotten dropped in the merge. It looks like the compiled application.css is missing my change in inbox.scss:

.track-icon {
  float: right;
}

Here's what I see in my dev environment:

What would be the best way to fix this?

[kytrinyx]

I'll recompile locally and see if it gets added.

[kytrinyx]

I think that worked. Thanks for catching that.

[bradhvr]

Great, thanks!
