test in java.py, should report if subpackages doesn't have a fully versioned dep on base package.

When running with --bug 805487, it fails to report that the package logback-examples doesn't have the required dep.

Also, when this test gets multiple hits, the output is a mess. Is should be something like
"Missing: Requires: %{name} = %{version}-%{release} in " [,pkg...],now the preamble is repeated creating some nasty lines.
