Propel entries missing from profiler if APP_DEV is on

[papatti]

The "Propel" section of the Symfony profiler is inactive, because connection is not in debug mode.

I attempted to fix it by adding

if ($this->container->getParameter('kernel.debug')) {
    $connection->useDebug(true);
}

in PropelBundle::configureLogging() to both read and write connections. This worked fine whith browser request, Propel queries appeared correctly in profiler, but caused a huge memory leak when executing queries in phpunit tests. In Propel's ConnectionWrapper::callUserFunctionWithLogging() both $callback(...$args); and $this->log($sqlForLog); increased memory usage by 17K for each query.

(Symfony 5.4.18, PHP 8.0.24, MySQL 5.7, PHPUnit 9.3.11)

Great job by fixing up PropelBundle btw! Really appreciate it!
