Files autoloader for symlinked package not copied or referenced correctly

[BrianHenryIE]

bootstrap.php

  "autoload": {
    "classmap": ["src"],
    "files": ["bootstrap.php"]
  },

in a symlinked package

 "repositories":{
    "brianhenryie/bh-wp-plugin-meta-kit":{
      "type": "path",
      "url":  "../bh-wp-plugin-meta-kit/"
    }

was not copied to the destination directory.

And the generated autoload-files.php referenced the original path:

require_once __DIR__ . '/Sites/bh-wp-plugin-meta-kit/bootstrap.php';
