In case of empty resource key use 'NOKEY' fallback

[visma-mrange]

I am not satisfied with my proposal but I thought we could discuss the issue a bit. For some reason I consistently get file-locking issues when running. I don't use the parallel option.

It's always the same files and they are related to enviroment tags file.

For some reason it seems that we end up regenerating the same file in two different paths. I think a better solution would be to make sure the environment tags are grouped together.

I didn't figure out how to do it but perhaps you have some ideas:

Path to file that files for us:

contracting.works\test\README.md

The content of the README.md file:

---
summary: Resources for tag test

## Values

|                                                                                                 |
|-------------------------------------------------------------------------------------------------|
|  |

The content of the file that ends up with a random name. I removed our identifiers although I don't think they are sensitive

I can do some more experiments later on grouping the files.

After debugging found the writer and the valueWriter got the same path because for some reason the resources key was empty string. In that case sets it to NOKEY now. Works on my machine.
