fix: SearchBar autofocus when click on clear btn

[MrSIHAB]

The search bar should automatically focused when 'clear search text' button is clicked. This is small tweak but usefull too. I do search, do some activities. Then search bar become unfocused. Then I click on clear search button and start typing my query, And then I see that Search bar is not focused. I have to manually click on the textfeild to focus it. This pull request will automatically focus search bar when someone click on clear search button. I made this changes from my experience.
