Dots in artifact names cause issues in generating proper fetch-artifacts-url.yaml file
**Describe the bug**
When an artifact contains dot in the name and it is used 
in the fetch-artifacts-url.yaml, the generated URL
is wrong and instead of preserving the dot it is converted to a slash.

Example artifact that is causeing troubles:

```
/usr/bin/brew call --json-output listArchives checksum=569870f975deeeb6691fcb9bc02a9555 type=maven
[
  {
    "build_id": 410568,

    "type_name": "jar",
    "artifact_id": "javax.json",
    "type_id": 1,
    "checksum": "569870f975deeeb6691fcb9bc02a9555",
    "extra": null,
    "filename": "javax.json-1.0.4.jar",
    "type_description": "Jar file",
