Wrong insert position for auto-generated code when using macros

[davelopez]

Currently, the expanded (all macros expanded) version of the document is used to determine the <inputs> and <outputs> of the tool when trying to auto-generate the tests (#73) or command (#77) sections.
While this is important to retrieve the real inputs and outputs of the tool, the exact insert position for the auto-generated code is also based on the expanded version, leading to a resulting insert position that does not match the 'unexpanded' document version.

We should keep both 'expanded' and 'unexpanded' versions of the document and use the 'unexpanded' one to calculate the insert position.
