Output format JATS adds linebreak in Author fields

[Thanathan-k]

While using the --format=jats option the output file of a .tex file will have strange added linebreaks in the authorfield of given-names.

See https://gist.github.com/Thanathan-k/4737da29913e6eeecb177dd2cf1fa651 for a very simple example.

This originates from an extra   (non-breakable space) in https://github.com/brucemiller/LaTeXML/blob/master/lib/LaTeXML/resources/XSLT/LaTeXML-jats.xsl#L532. I have made a PR to fix it, but I am not sure why it was there in the first place.
