FIO-8819: Removed duplicate request on form manager search

Description

Issue: The formManager search calls this.formGrid.pageChanged, which internally calls the refreshGrid method. The refreshGrid method makes an HTTP request to get forms. Additionally, the formManager search also calls this.formGrid.refreshGrid. This results in two refreshGrid calls and two HTTP requests with the same data. Furthermore, the variables this.gridQuery and this.formGrid.query are equal because this.gridQuery is passed as a prop to this.formGrid.

Regarding the clearSearch method: when we manually reassign this.gridQuery to another object, this.gridQuery and this.formGrid.query are no longer equal, so we need to reassign this.formGrid.query before making the API call.

Solution: Remove the second refreshGrid call.
