SOLR-12901: UH: handle highlighting no fields
Fixes CustomHighlightComponentTest.
> Make UnifiedHighlighter the default

> Project: Solr
> Issue Type: Improvement
> Components: highlighter
> Reporter: David Smiley
> Assignee: David Smiley
> Priority: Blocker
> Fix For: 9.0

> Time Spent: 20m

> I think the UnifiedHighlighter should be the default in 8.0. It's faster and
> more accurate than alternatives.
> The original highlighter however has some benefits:
> * Different passage/snippet delineation options; somewhat more flexible.
> Though no i18n BreakIterator based one.
> * Seems to handle some "special" Queries and/or QueryParsers by default
> better -- namely SurroundQParser. Though SOLR-12895 will address this UH
> issue.
> * Considers boosts in the query when computing a passage score
> * hl.alternateField, hl.maxAlternateFieldLength, hl.highlightAlternate
> options. Instead the UH has hl.defaultSummary boolean
> See
