BUG/MINOR: counters: do not untrack counters before logging

Baptiste Assmann reported a corner case in the releasing of stick-counters:
we release content-aware counters before logging. In the past it was not a
problem, but since now we can log them it, it prevents one from logging
their value. Simply switching the log production and the release of the
counter fixes the issue.

This should be backported into 1.5.
