Package Tools Files Are Broken

Legacy tools files within a packaged block are broken. The call to `$env->getPath()` on line 103 of **view.php** was returning a path relative to the **concrete** directory instead of the **packages** directory. I think this is because nothing was being passed in for `$this->themePkgHandle` (which makes sense if the package is not a theme). This fix was simple to implement, appears to work, and doesn't seem to break anything, but a core member should make the call as to whether this is the right way to go about it.
