The execution results are not being imported to the same Test Execution, if using the Test Parameterized option and the parameter is not filled

When using the feature "This project is parameterized" and use this parameter to specify on which Test Execution the Execution Results should be imported, if the parameter to specify the Test Execution is not filled before build the job on Jenkins, it will create different Test Executions for each execution results file.

Steps to Reproduce

Step	Result
Create a project and configure it as a Parameterized project
Use the parameter on the Test Execution and check the option "Import to same Test Execution"
Have more than one execution results file to be imported
Build the job without filling the parameter
The results were imported, however it were created three different Test executions (one for each execution results file)
