Description of problem:
'Required' functionality is not working for smart class parameter type 'boolean'.

Version-Release number of selected component (if applicable):
Sat 6.2 snap 19.1 GA

How reproducible:
Always

Steps to Reproduce:
1. Set default value for parameter type 'boolean' to true.
2. Select required checkbox to validate that value shouldnt be blank.
3. Create a matcher with empty/blank value.
4. Attempt to submit it.

Actual results:
The parameter is submitted by setting matcher value to 'false' automatically.

Expected results:
1. The parameter should not be submitted and should throw an error 'Value can't be blank'.
2. Autoset of boolean value to false for matcher should not happen.
