Invalid path handling when using tokens

In elfinder_filesystemconnector() when the volumes are collected, the paths are handled as relative paths when they do not start with a /. This logic breaks then the path starts with a token. For example, a path of "[mymodule:mytoken]/images" would be handled as a relative path, even though the token in the beginning may resolve to something that starts with /. As result, these token based absolute paths get prefixed with the path of the Drupal files directory path, and do not work as expected.

I think the token substitution needs to happen before this relative directory check is done. I am attaching a patch to address this.
