[BUGFIX] fix build stability

[stefanpenner]

This prevents fastboot from constantly writing its package.json if it has not changed.

LGTM. I think there are existing tests around the package.json. What other tests did you have in mind?

I think there are existing tests around the package.json

Unit tests, the existing ones are too high level to add proper coverage (and also quite slow and brittle)

Working one them now.

@kratiahuja I have added tests targeting the build and build stability. (If you are good with it, feel free to merge and release)

---

Would likely recommend we transition more and more of the tests to more targeted tests like this. Rather then the end to end tests we have now. I feel we have better confidence with the tests, easier to pin-point issues, easier to add additional scenarios etc, then the existing approach.

Tried this also, and can confirm this works perfectly! 👍

For the record: this also fixes the issue that CSS hot reloading was not working correctly, the browser would always do a full reload even if just some CSS/Sass files changed.
