Prevent SearchInput component from triggering esc key action if query is empty

[rithviknishad]

Describe the bug
Currently when there's no search query, and if we press empty, it refreshes the page by explicitly setting the query to empty in query params.

To Reproduce
Steps to reproduce the behavior:

1. Go to facilities page
2. Press Esc

Expected behavior
No change to be made in the query params if search is already empty. (Avoid triggering the action in the first place)
