Inplace operation within a PythonAlgorithm raises an error

Description

Attached is a simple python algorithm that calls Scale internally. It fails if the input & output workspace are the same. 

data = [1.0,2.0,3.0]
test_ws = CreateWorkspace(DataX=data,DataY=data,NSpec=1,UnitX='Wavelength')
ScaleWrap(InputWorkspace="test_ws", OutputWorkspace="test_ws")

Ensure Python sub algorithms have correct child status. Refs #6258

They were not children and hence the workspace locking was trying to double lock and Poco threw an exception when it tried.
