Master fails to send crash notification on crash

[Cody A.W. Somerville]

The call to notifications.notify_crash fails to pass in configuration to use as second argument resulting in following traceback that is only displayed if the offspring-master is ran in debug mode:

  File "/usr/lib/python2.7/threading.py", line 552, in __bootstrap_inner
    self.run()
  File "/srv/lib/offspring/master/master.py", line 69, in run
    mailer=self.mailer)
TypeError: notify_crash() takes at least 2 arguments (2 given)

In master.py we see:

                notifications.notify_crash(
                    "Lexbuilder Master (Build Queue Dispatcher)",
                     mailer=self.mailer)

while the function signature for the function is:

def notify_crash(component, config, mailer=mail_notification)
