Fix undo cleanup failing for "parameter with value" steps (#3500)

The "request contains parameter with value" step was not storing
values in pathParameters, causing undo operations with path-origin
parameters (e.g. organization_binding_id) to fail with
"Path parameter not found". Match the behavior of the
"parameter from" step by storing in pathParameters.
