Fix function with multiple namespaces

[VincentLanglet]

Hi @theofidry, I discovered a bug with the php-scoper.

Before the fix, I get

namespace Acme\Emca {
    if (!function_exists('Acme\Emca\foo')) { function Emca\foo() { return \Humbug\Acme\Emca\foo(...func_get_args()); } }
}

which is crashing.

Thank you @VincentLanglet, I'll try to check the CI ASAP to fix it to get this merged

Should I fix the test on this PR @theofidry ? It seems to mainly be CS issues

[theofidry]

@VincentLanglet the CS yes (I think it's related), but the test failures looks unrelated so in a different MR. Sorry I'm a bit overwhelmed IRL between visists and moving and stuff
