Sqlite3 uninstrumentation does not work properly

Describe your environment
Python 3.9

Steps to reproduce
Spans keep being created after I call uninsturment:

       import sqlite3
        from opentelemetry.instrumentation.sqlite3 import SQLite3Instrumentor

        SQLite3Instrumentor().instrument()
        cnx = sqlite3.connect(":memory:")

        self.memory_exporter.clear()
        SQLite3Instrumentor().uninstrument()

        stmt = "CREATE TABLE IF NOT EXISTS test (id integer)"
        cursor = cnx.cursor()
        cursor.execute(stmt)
        spans = self.memory_exporter.get_finished_spans()
        self.assertEqual(len(spans), 0)

But if I move the sqlite3.connect after the uninsturment, like this:

        SQLite3Instrumentor().instrument()

        self.memory_exporter.clear()
        SQLite3Instrumentor().uninstrument()

        stmt = "CREATE TABLE IF NOT EXISTS test (id integer)"
        cnx = sqlite3.connect(":memory:")
        cursor = cnx.cursor()
        cursor.execute(stmt)
        spans = self.memory_exporter.get_finished_spans()
        self.assertEqual(len(spans), 0)

it works as expected.
The problem is when instrumented sqlite3.connect returns "get_traced_connection_proxy"
and after uninstument i still use the same connection that I opened before and the hooks still work

What is the expected behavior?
spans will not create after call uninstrument

What is the actual behavior?
still get spans after uninstument
