Added a button to clear all recent searches. (#1487)

* Added a button to clear all recent searches.
- Deletes all the searches for the current user from the database.
-  Delete icon placed at the end of subreddit name layout in the activity search layout(I couldn't find a better place for it).
_Icon visible only when there are recent searches.

* Confirmation dialog shows when clearing all search history.
