Fixed replaced_task_nesting

[Nusnus]

The replaced_task_nesting (docs @ New in version 5.2. ) was missing from the request because it wasn't parsed correctly over the call stack. This made the whole feature invalid as you always lost the replaced_task_nesting value which made it reset to zero.

This PR fixes the handling of replaced_task_nesting and also adds integration tests for the feature that didn't exist before.
