Uninitialized value warning from Venn::Log::L4PWrapper::debugf

Use of uninitialized value $_[0] in sprintf at /var/tmp/venn-core-1.0.0-build011-build/x86-64.rhel.7
/5.18/source/core-1.0.0/blib/lib/Venn/Log/L4PWrapper.pm line 98, <$fh> line 1.

There's a reason perl critic whines at you for not unpacking @_, but you told it to shut up, so... This is what you get :-)

This occurs twice in the test suite output.
