Fix summary rendering when no valueList is supplied

[rmccar]

What is the context of this PR?

Have updated the summary macro to add a class that sets the width of the actions to be double width to take up the space that the valueList would take up. This fixes a misalignment when valueList is not provided. Also added tests for this and a missing test for the equivalent in actions.

Have also updated the example so that these scenarios are covered so if this ever happens again it should be picked up and have updated the documentation because either valueList or actions should be set to make the html correct from a semantic standpoint.
