Improve Deleting Privilege

[kolatubosun]

@dadepo For some reasons, some homographs have been created in the database due to some errors at the beginning of the work. One of them is Ṣoyinka/Soyinka divide which is unnecessary. But for some other reason, one isn't able to delete either of them. It is the same issue with some other earlier problematic entries. For this reason, please make it easy to delete entries from the search console.

For instance (see screenshot), in this view, I should have checkboxes beside the names so I can go to which of the Soyinka entries I don't want anymore, and get rid of it.
