start-time and end-time almost same in generated test reports.

• Patch Submitted:

  Yes

test.xml target "gen-xml-results" should depend on "test" rather than "init".
Otherwise, ant seems to evaluate <tstamp prefix="test-run.end"> at about the
same time as "init" target, thus rendering meaningless the test-run end-time.

I'm attaching a trivial patch to fix this.
