Fix bookmarks

Overview

Fix BE bookmark deletion.

Right here the .splice method is being used with the indexOf operator. The issue is that indexOf returns -1 if the post is not found in the user’s saved posts. But splice will treat -1 as the last index of the array, and not throw an error, so it just removes the last bookmarked index.

Fix by throwing an exception when -1 is the found index. Also compares posts by IDs only which should be more reliable than comparing the entire object. Lastly, adds 1 as the second argument to .splice so it only deletes one item!
