Modify RecentlyAddedListComponent and its copy

[marlo-longley]

Closes #1316

[marlo-longley]

I could be convinced that testing for expect(component.count).to eq(13) hardcoded is a bad idea and will make adding unrelated new docs annoying in the future. I just wanted to make sure the component was working.

Why would it be over (that number should be exact). Shouldn't it just be There are 36 datasets?

[marlo-longley]

I just mean if I'm working on something else and add a new fixture, this test will fail and be annoying.

[dnoneill]

No sorry that wasn't clear. The copy says There are over <b>%{sets} datasets</b> in EarthWorks. but that isn't actually correct there are exactly %{sets} not over.

[marlo-longley]

I seeeee. Thanks!

[marlo-longley]

@dnoneill fixed.

[jcoyne]

@marlo-longley this needs a rebase

Seems like this is exactly what happened. I'm going to just remove that test.

Perfect, thank you for covering Nick!!
