Death by Exception when processing aliased Trait methods

[crussell52]

If APIGen tries to parse a class which uses a Trait and aliases a method, then it dies with the following error:

Argument 1 passed to ApiGen\Template::getMethodUrl() must be an instance of ApiGen\ReflectionMethod, null given

Here is the relevant portion of the debug output (some directories are masked since this is on a work server):

To reproduce, create a file with the following code and attempt to run apigen against it:

<?php

trait MyTrait
{
  public $myVar;

  public function myMethod()
  {
    // Do something.
  }
}

class Foo
{
  use MyTrait
  {
    MyTrait::myMethod as myAliasedMethod;
  }

  function myMethod()
  {
    // Do local stuff.
    // Run trait method.
    $this->myAliasedMethod();
  }
}
