Fix local source absolute resource URL

[dormeiri]

Absolute resource URL for local source is not working.

Steps to reproduce:

1. Make a noodle config file with local source and absolute URL. (appendix 1 for example)
2. noodle run

Expected

Scan is working, resource's source folder and relationships links are good.

Actual

Error: ENOENT: no such file or directory, scandir '/Users/***/monorepo/examples/basic/Users/***/noodle-graph/monorepo/examples/basic/someService'

As you can see the absolute path was concatanated with the current working directory.

Appendix 1 config example

{
    "resources": [
        {
            "id": "some-service",
            "url": "/Users/***/noodle-graph/monorepo/examples/basic/someService",
            "source": "local"
        }
    ]
}
