* test/rexml/test_encoding.rb
  (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.
