Pyvomi module failing in connect method

[saranyasridharan]

Describe the bug

while trying to connect to vcenter using pyvomi module, noticed the below issue.
class StubAdapterAccessorMixin has no attribute '__init__'
There is no init method found in this file

Solution:
It worked when I commented out the below line
https://github.com/vmware/pyvmomi/blob/master/pyVmomi/SoapAdapter.py#990
We need to remove it I believe

Reproduction steps

1. Replace the hostname,username,password with proper values
2. Run the below code

from pyVim.connect import SmartConnect
c = SmartConnect(host="hostname", user="username", pwd='password')
print(c.CurrentTime())

Expected behavior

vcenter connection should be established without throwing any error. As per the sample program, it should print current time after connecting to vcenter.
