Use Relative Path in model_file in Tests

[RichardWhitfield]

When defining the location of the model_file in a test yaml file, the expected behaviour is that the path to the model_file is relative to the test file where it is referenced but seems to be relative to the directory where the command originated.

For example: I have a folder structure as below:

• src
  • schema.fga
• tests
  • tests.yaml
  • data.yaml

In my tests.yaml file I define the location of the model_file as ../src/schema.fga.

If I execute this command:
fga model test --tests .\tests\tests.fga.yaml
from the root directory of the repo I get the below error:
Error: failed to read file ../src/schema.fga due to open ../src/schema.fga: The system cannot find the path specified.

If I execute the similar command:
fga model test --tests .\tests.fga.yaml then the command successfully executes.
