Mapping parameters in the MIA task using a query task as child task #506

Describe the bug

The bug refers to MIA task. When a query task is added to a MIA task, it is possible to configure the parameters to map the required parameters in the query task with the parameters created in the MIA task.

This configuration is done using with a form showed at the screenshot

This form allows to map a MIA parameter (left drop-down list) with a query task parameter (right drop-down list). The items included to the “Child task parameter” refers to the label defined at the query task, as shown in the screenshots.

Assigning parameters to the MIA task requires that child task parameter be the parameter name (not the parameter label).

When label parameter and name parameter are the same at the query task, the MIA mapping parameters work fine, but if they are different, they do not.

To Reproduce
Steps to reproduce the behavior:

1. Create a query task with a parameter, when name parameter and label parameter are different
2. Try to assign a MIA parameter with the parameter created at step 1
3. MIA fails because it cannot correctly send the MIA parameter to the query parameter

Expected behavior
The drop list of “child task parameter” should use the name parameter as the value to map the parameter with MIA parameter.
