(REXMLTests::EncodingTester#test_parse_utf16): Use meaningful
test name. "ticket" in the old test name means the ticket in
REXML's issue tracker. The REXML's issue tracker was gone. So
"ticket" is meaningless.
* test/rexml/data/ticket_110_utf16.xml: Rename to ...
* test/rexml/data/utf16.xml: ... this.
