Connman test case was failing as Autoconnect was connecting the ethernet before the Connect method was called.
This caused the Error: Already connected which was making the test case fail.

Fix: Autoconnect property has been made false in the initial steps. This will allow the Connect method to work properly
and the property has been made true after the execution.
