Test Latest TextTagger in other languages/scripts

[mubaldino]

Describe the bug
TextTagger usage with languages other than English.

To Reproduce

• Java or Python version: Any Java (openjdk 8 and 12)
• Usage: Arabic text produces a "zero-length token" exception from TextTagger process()
• Data input:
• Did you enable logging (level = DEBUG)?
• Other notes:

Expected behavior

More reasonable behavior is expected from TextTagger -- its possible the whole Solr 7.x assembly needs to be replaced with a clean setup and fully reindex data.
