fix: include original coordinates in support code library

[davidjgoss]

🤔 What's changed?

Always initialise the support code library with original coordinates so it can be loaded again in child processes.

Previously, when using the API, calling loadSupport and using the result in runCucumber with the parallel option would result in a state where:

• The parent (coordinator) process has the support code loaded
• It is happy for test cases to run since it can see they have matching step definitions
• The child processes don't have the coordinates, so they don't load the support code

And this would be followed by obscure errors as noted in the linked issue.

⚡️ What's your motivation?

Fixes #2196.
