trace_processor: handle null partition keys in span join

If there are any null partition keys, simply skip them all. This ensures
that we don't end up with 0 partition keys mistakenly in the span
output.

We cannot do any better than skip as NULL in SQL means "unknown" so we
cannot assume any partition value for these NULLs.
