Title: Fix bug in formats tests when enabling debugging using envvar PICARD_DEBUG

Calling log.debug() causes script to stop because of threads aren't create as in
true Tagger class (here we are using a fake one for test purpose).

As a workaround, re-define those functions so they don't use threads.
