test: setup logging during nmtst_init_assert_logging()

Before, when having a test with nmtst_init_assert_logging(),
the caller was expected to setup logging separately according
to the log level that the test asserts against.

Since 5e74891b58, the logging
level can be reset via NMTST_DEBUG also for tests that
assert logging. In this case, it would be useful, if the test
would not overwrite the logging level that is set externally
via NMTST_DEBUG.

Instead, let the test pass the logging configuration to
nmtst_init_assert_logging(), and nmtst will setup logging
-- either according to NMTST_DEBUG or as passed in.

This way, setting the log level works also for no-expect-message
tests:

  NMTST_DEBUG="debug,no-expect-message,log-level=TRACE" $TEST
