InfluxDB: Always Write Out Metadata

Browse Source 
Previously the logic would just bail out if no performance data was associated with a
check, the problem being that check metadata was skipped too.  This rearranges the code
to dump out performance metrics if they exist, then dump out metadata if requested.  This
also fixes an issue whereby metadata was being sent for every performance data in the
check result, rather than just once, so we save a bit of bandwidth as a result.

fixes #12276
