Fixed crash if logging happened in unit tests

Browse Source 
The patch initializes logging in unit tests. Previously, unit tests did
not initialize logging and other subsystems, just resources. But
resource_init() could under certain circumstances trigger logging and
cause crash.

The bug was Found by Jakub Ruzicka, dissected by David Petera and Maria
Matejka, disguised as failing build for Debian arm64 in pbuilder
emulation which did not like disabling THP.

Fixes #42.
