Display display names in gradle test output (#2578)

The default test output always uses the name, so you end up with:
```
LuceneHighlighterTest > highlightsSpecialCharacterTerm(String, Analyzer, Analyzer, String) > com.apple.foundationdb.record.lucene.highlight.LuceneHighlighterTest.highlightsSpecialCharacterTerm(String, Analyzer, Analyzer, String)[1] STARTED

LuceneHighlighterTest > highlightsSpecialCharacterTerm(String, Analyzer, Analyzer, String) >
com.apple.foundationdb.record.lucene.highlight.LuceneHighlighterTest.highlightsSpecialCharacterTerm(String, Analyzer,
Analyzer, String)[1] PASSED
```

Which is not great, this adds our own logging that renders the
display name. So the above would become something like:
```
LuceneHighlighterTest > highlightsSpecialCharacterTerm(String, Analyzer, Analyzer, String) > AlphaCjk-Synonyms,Ϲ STARTED
LuceneHighlighterTest > highlightsSpecialCharacterTerm(String, Analyzer, Analyzer, String) > AlphaCjk-Synonyms,Ϲ
SUCCESS (0ms)
```

As you may note, I took the liberty of adding the duration of the
test in milliseconds.
