Describe the bug It seems that the Feature Context is not inherited with implementing steps using Scenario Outline but I cannot trace the cause.

Environment and Version

• OS (incl. terminal and shell used): Windows 10 Enterprise Build 17763, VS Code Integrated Terminal (bash)
• Python Version: Python 3.8.3
• radish Version (radish --version): 0.13.2

To Reproduce I have the following code in terrain.py:

@before.each_feature()
def initialize(feature):
    feature.context.index = 0

In one of the steps implementation, when step.parent.parent.context is invoked:

camera_index=step.parent.parent.context.index

I get the error:

AttributeError: 'Context' object has no attribute 'index'

I tried to print out the following:

print(step.context.__dict__)
print(step.parent.context.__dict__)
print(step.parent.parent.context.__dict__) 

And it yielded these:

{'constants': []}
{'constants': []}
{'constants': []}

Again, I only encounter this when the Scenario uses Scenario Outline and the parent contexts are accessed within the step implementation.

Expected behavior Contexts created in the Terrain can be normally accessed even if the Scenario is defined as "Scenario Outline".
