jabref: export to Harvard/RTF incorrect when name contains (properly escaped) "and"

JabRef version 3.2

• I have tested the latest development version from http://builds.jabref.org/master/ and the problem persists (JabRef-5.0-dev–snapshot–2018-11-23–master–742cfce7e.jar)

The export filter interprets all "and"s in name fields as breaking multiple names even when the author is properly escaped with curly braces.

Steps to reproduce the behavior:

1. consider the bibtex

@article{test,
  author = {{Organization for Economic Cooperation and Development}}
}

1. verify that latex+biber properly output “Organization for Economic Cooperation and Development” as author
2. export with Harvard filter and find “Organization for Economic Cooperation & Development”.
3. change name to {{Organization for Economic Cooperation and Development and other stuff}} and rejoice at “for Economic Cooperation, O.; Development & other stuff”

Clearly, the export plugin does not honor the double curly braces that should prohibit breaking names.

I haven’t found any other way of quoting the “and” to avoid breaking the name into multiple names that are then recombined, either.
