Description
___________
 
There was an attempt to use the ``Sqlite3`` database, while it is not yet initialised, or already closed. 

When extending the ``Sqlite3`` class, make sure the constructor calls the parent constructor, so that ``Sqlite3`` is actually initiliazed.

Note that the ``Sqlite3`` object was not unset yet, so it still exists. It would have been another error then.

Example
_______

.. code-block:: php

   <?php
   
   // Not yet initialized object
   $sqlite3 = new class (':memory:') extends Sqlite3 {
       function __construct() {}
   };
   $sqlite3->query('SELECT 1'); // OK
   
   // already closed object
   $sqlite3 = new Sqlite3(':memory:');
   $sqlite3->query('SELECT 1'); // OK
   $sqlite3->close();
   $sqlite3->query('SELECT 1'); // Not OK
   
   ?>

Solutions
_________

+ Check that the parent class of an extended Sqlite3 class is actually called.
+ Check that the parent class was not already destroyed.
+ Check that whole object is destroyed, not just the parent class.
