Bug report

Describe the bug

Performing a select operation with a filter after deleting the last row in a table results in an error.

To Reproduce

Steps to reproduce the behavior, please provide code snippets or a repository:

1. Insert an item

      // Insert an item
      await mockSupabase
          .from('posts')
          .insert({'id': 1, 'title': 'To be deleted'});

2. Delete the item

      await mockSupabase.from('posts').delete().eq('id', 1);

3. Attempt to select an item with a filter

      final posts = await mockSupabase.from('posts').select().eq('id', 1);

4. Bad state no element error thrown when setting up FilterParser.parseFilter since the returning rows list is empty. See line 549.

Expected behavior

An empty array should be returned if the returningRows list is empty when trying to apply filters.
