[FIX] web: Fix the zoom image stick top on search of employee.

Currently, the Employee picture stays on top of the card of the employee
we're looking for. The image does not disappear after a search is validated.
Steps to reproduce:
 >> On employee kanban focus cursor on search panel, then mouse over
to employee image so it will be zoomed, now without mouse leave just
type in the search panel and enter, the big zoomed image stuck on
screen and don't even know how to make it go away.

So in this commit, We fix that on keudown hide the zoom image so
when user search on search panel it will hide the zoom image.
OnShow of zoom bind the generic even keydown and on that just
hide the image so it should not stick on screen.
