v0.1.16: incorrect path generated

[florianduros]

Hi,

With the v0.1.16, the generated paths in the SUMMARY.md are incorrect. I don't face the issue with the v0.1.15.

I have the following folder structure:

- docs
    |-- project 
          | -- SUMMARY.md
          | -- README.md

The SUMMARY.md has a link to the README.md:

- [Introduction](README.md)

Running the command:
$ mdbook-combiner -m docs

The generated SUMMARY.md has the following content:

- [Introduction](README.md)

Instead to have an absolute path to the README.md like:

- [Introduction](myabsolutepath/docs/project/README.md)

Thanks for the bug report, I'll have a look at this later today.

I think this should be fixed in 0.1.17
