Fix broken travis build by modifying the `--resource-path`

When specifying the resource path via `--resource-path` the template will be searched there since pandoc 2.9.2.1.
To fix the broken travis build (`Could not find data file templates/eisvogel.latex`) the
current working directory `.` is included in the resource path for pandoc to find the template again.
