Log all transactions including those with uncertain status or no sent response.

Excluding those transactions from access log hides valuable information.

For example, it hides certain aborted client transactions which sometimes
indicate Squid bugs or configuration problems that the administrator can fix.
It also leads to wrong statistics reporting if the reporting tools are based
on access logs information.
