Schema browser improvement for all entities

In SQL explore/SQL transforms when a user searches for a table in the schema browser and that table is not present then a message should be displayed saying the table is not present, instead, it returns nothing which creates confusion for the user whether the schema browser is working or not. So to avoid confusion for users we can add a message.


An improvement could be adding a message if the table is not present while searching for the table in the schema browser.
