fix TypeError(s)

[git-abdullah]

Fixed these two errors, removed parent argument and added arg to init()

Traceback (most recent call last):
  File "D:\.temp\EmuGUI\emugui.py", line 1282, in startVM
    dialog = StartVirtualMachineDialog(self)
  File "D:\.temp\EmuGUI\dialogExecution\startVirtualMachine.py", line 26, in __init__
    super().__init__(parent)
TypeError: object.__init__() takes exactly one argument (the instance to initialize)

Traceback (most recent call last):
  File "D:\.temp\EmuGUI\emugui.py", line 1159, in createNewVM
    dialog = NewVirtualMachineDialog(self)
TypeError: NewVirtualMachineDialog.__init__() takes 1 positional argument but 2 were given
