Søren Eggert Lundsteen Olsen 25a67cb98b Stop SQLInsight deadlocking itself, and stop reporting its own deadlocks 
At a customer whose repository sits on a monitored instance, the agent
reported 12 deadlocks that were its own: two instances' monitors save
findings in parallel, one transaction each, and while insight.Findings is
small SQL Server scans it, so the two lock each other's rows.

- SaveRuleResultsAsync takes an exclusive application lock for its
  transaction (the agent is the only writer; a save takes milliseconds)
  and retries if chosen as deadlock victim anyway
- repository connections are named "SQLInsight Pro (repository)"
- deadlocks where every participant is SQLInsight Pro are not reported
  (the read position still moves past them); any other session keeps it

The new integration test (two instances saving 25 rules x 40 rounds in
parallel) failed 2 of 2 without the fix and passed 5 of 5 with it.
