Remove duplicate DevGuide example FirstConnection

While cleaning up "LibreOffice DevGuide: Chapter 1 - First Steps" in
the TDF Wiki, I understood that only 3 examples were compiled via the
Makefile, but there were 4 java files. It turned out that the
FirstUnoContact.java and FirstConnection.java are essentially the
same. I removed the second one, as it was not built, and was not
referenced elsewhere.
