Handle GetCompletionsAsync cancellation better

[JustinGrote]

Type: Bug

This is more of PSES issue but filing here to include context.

Getting lots of exceptions in the PSES output pain for completion requests being cancelled. I assume they are being pre-empted but maybe handle this type of exception in a more specific way?

Ah, well good news is we're catching it and just what's going on is a too-verbose log message:

            // We can't do anything about completions failing.
            catch (Exception e)
            {
                _logger.LogWarning(e, "Exception occurred while running handling completion request");
                return new CompletionList(isIncomplete: true);
            }

Instead of a warning that should either not exist or just be a diagnostic. I'll get on it!
