tests: fix worker thread initialization

from threading.thread __init__:

    This constructor should always be called with keyword arguments.

    If a subclass overrides the constructor, it must make sure to invoke
    the base class constructor (Thread.__init__()) before doing anything
    else to the thread.

Type: test
