Subject: [PATCH] Disconnecting the database connection after testing (#49327)

* Disconnection after testing with traits for database testing

* Revert "Disconnection after testing with traits for database testing"

This reverts commit 71c6653640d56d65d88d5addc85731974430e6d0.

* Disconnection at teardown

* No need to disconnect for individual traits

* fix: Behavior when run without database

* Avoid changing the behavior before fixing as much as possible.

* Update TestCase.php
