contributor search returns no results when name contains "-"

Adam asked on https://github.com/folio-org/raml-module-builder/pull/489:

I hope that the replace-stuff will not hinder indexes from being used.

This shows that the index t_to_tsvector_idx is used because the replace is on the right hand side of @@ only. This is similar to jsonb->>'title' LIKE f_unaccent('abc xyz').

Asked to review so we can merge before the end of the sprint.

Postponed to q3.2-2019 as requested by Jakub.

This also works for UUID matching:

My implementation idea is this:

Replace space by <-> and replace special characters (& <-> :) by other punctuation.
Pass it through to_tsquery.
Replace any & by <->.
