Muted errors are still visible for the handler installed via set_error_handler. So you can just add something like this to your bootstrap file:

set_error_handler(function ($errno, $errstr, $errfile, $errline) {
    echo "$errstr at $errfile($errline)\n";
});

or, better,

set_error_handler(function ($errno, $errstr, $errfile, $errline) {
    throw new ErrorException($errstr, $errno, 1, $errfile, $errline);
});

which also would display the stack.
