Remove nested BOOST_LOG_TRIVIAL to fix erroneous log level display

[taclane]

In trunk-recorder, some BOOST_LOG_TRIVIAL(info) entries are showing as trace even when the log level is set at info.

As noted here, nested BOOST_LOG_TRIVIAL calls override the severity display of the parent call.

This is commonly seen in "Concluding Recorded Call" messages and other things displaying "Last Update: X s" because Call_impl::since_last_update() has a BOOST_LOG_TRIVIAL(trace) while passing back the integer result.

There may be other nested boosts to uncover, but this one was fairly prevalent since it occurs at least once with each call.

Interesting! I had been wonder about this. I will have to keep an eye out for others. Thanks for catching this
