Fix broken code for ternary operator with class instantiation with omitted parentheses

[panzer-punk]

Hello there!
I have encountered broken code generation with the new operator inside ternary operator.
ReflectionClosure->getCode() skips the ':' symbol if constructor parentheses are omitted.
Sample code:

function () {
    $flag = true;
    return $flag ? new RegularClass : new RegularClass;
}

will result a broken code:

function () {
     $flag = true;
     return $flag ? new \Tests\Fixtures\RegularClass  new \Tests\Fixtures\RegularClass;
}

This can be reproduced in 1.x branch as well.

3rd param of true should be passed to in_array, to use a strict comparison.

Done.

@GrahamCampbell Should I do the same PR for 1.x?
