Added correct resolver for classes with aliases out of context

[Pixelycia]

For example:

<?php 
namespace somens;
use some\other\ns;
class A {
   public function(): ns
   {...}
}

ns will be resolved correctly as some\other\ns not somens\ns.

Such as

<?php 
namespace somens;
use some\other;
class A {
   public function(): other\ns
   {...}
}

ns will be resolved correctly as some\other\ns not somens\other\ns.

Could you please add a number of tests to cover this new scenario.

The Travis CI build is failed.

I think it also checks them and fix the failed CI build.

@jaapio Is this still an issue?

[jaapio]

I don't expect this to be an issue a test has been added in March last year. This test is still passing so I don't know what the original author's issue was. It could be that it was resolved in between with a separate pr.

I will close this PR. @othercorey please open an issue if you have a problem with this library. I will try to respond as soon as possible.
