Remove --test_summary=detailed option

It seems that bazel doesn't report whether or not test result was
cached and the execution was skipped, when this option is passed,
so switch to the default test summary (short), e.g.:

  //javatests/com/google/gerrit/acceptance/server/mail:MailIT \
  (cached) PASSED in 19.6s
