ETT-1840: Fixes for title summary table

[aelkiss]

This addresses the reported issue of having extraneous format values, since the catalog extracts additional formats from various MARC fields in addition to the format extracted from the leader in a similar style to hathifiles.

• Query by format: catalog currently includes many formats we don't want, and there's no way to facet on (say) the first value of the format field; we would need to index that separately, and may want to do so in the future

Along the way I also fixed a couple other issues:

• Add facet.limit=-1 to ensure we're getting all values (the final count does differ and the tests will fail if that isn't there, subject to the vagaries of the sample catalog solr)

• Add facet.missing=true so we get counts of items with one or more facets with null values (this we can test)

If I remove the binding.irb that is causing the tests to fail, I still get a failed test in solr_pivot_facets_spec.rb line 39 with 1319 not being in the 1400-200 range -- not sure if that's due to a change in the sample catalog or just to SolrPivotFacets fixes. I originally just wanted to capture that there would be "a lot" of rows, so maybe pushing the range to be_between(1000, 2000) would be supple enough.

I thought I already changed this, but maybe the commit got lost. Fix incoming...

Fixed & force-pushed. I'll re-request review once tests pass.

Looks good now. I would recommend following up with the change mentioned at the bottom of bin/refresh_title_summary_table.rb re SimpleCov since the updated version is complaining now, i.e., replace # :nocov: with a # simplecov:disable and # simplecov:enable pair.
