Query params are cleared every time the user opens the Filter modal

Description

After #384 implementation, a minor bug is also a suspect of this slow modal opening.
Whenever we open the Filter modal, the query params are cleared, which eventually clears the current filter & sort as well.
It causes the ContactList component to be rerendered.

Additional Information

If this bug is solved, there's a high chance that the slow modal opening will be resolved.
