SW: Don't log if no association

We define logging levels in DEVELOPING.md[1], an error is "Something
went wrong, and we weren't able to give the expected response. Service
is still operational. "error" should be used for unexpected conditions
that prevented bmcweb from fulfilling the request. "error" shall be used
for 5xx errors.".

This clearly isn't an error since we just ignore not having an
association and move on. Moved these traces to DEBUG. Andrew mentioned
these cluttering the journal when running CI.

Tested: This is changing a Logging Level only.
