Fix non regression test

[VincentLanglet]

While working on #5386 I understood why the fix seemed to introduce a regression on bug-14249 file.

It's because the test

function doTemplated(): void {
	$f1 = assertIfTemplated(...);
	$f2 = 'Bug14249\assertIfTemplated';

	$v = getMixed();
	assertIfTemplated($v, true);
	assertType('true', $v);

	$v = getMixed();
	$f1($v, true);
	assertType('true', $v);

	$v = getMixed();
	$f2($v, true);
	assertType('true', $v);

	$v = getMixed();
	assertIfTemplated($v, false);
	assertType('false', $v);

	$v = getMixed();
	$f1($v, false);
	assertType('false', $v);

	$v = getMixed();
	$f2($v, false);
	assertType('false', $v);
}

is basically wrong.

Since getMixed is considered pure by default, it will return the same value.
If you call assertIfTemplated($v, true); the first time, it's expected to consider that getMixed will allway return a truthy value.

Then assertIfTemplated($v, false); would gives NEVER.
