Remove filterered stories from test

[zb-sj]

My sub test only needs one story to test but the current tag filtering implementation creates redundant describe.skip(${title}, () => { it('no-op', () => {}) }); as per makeDescribe

It wastes noticeable time just to skip those tests.

Wouldn't it be better not to generate a description for filtered tests? I see there is skipTags for the exact purpose.

Please let me know what you think and I could probably make a quick PR for this.
