Remove skipped examples in filtered issues feature spec
We perform a ton of expensive setup in this spec, via both before and
let!. When we use skip inside an it block, rather than skipping
the block entirely via xit, we still perform this expensive setup,
only to do absolutely nothing with it, resulting in wasted time.
Minutes, in this case.
Further, these specs have been sitting in our test suite for about seven months now, so the likelihood of them being addressed soon seems low.
