Summary

Previously if yarn test was run without first having run yarn build, these three test suites would fail with over 1000 lines of unclear console output. Now, later tests are stopped from running to reduce verbosity, and a more contributor-friendly error message displayed instead.

Note: We unfortunately can't handle this case in beforeAll(), since even if it throws, later tests in the same file are still run:
jestjs/jest#2713

Test plan

Output of yarn test previously:

test: Fail early if the local yarn build is missing
9177f2f 
Previously if the tests were run without first having run `yarn build`,
these three test suites would fail with over 1000 lines of unclear
console output.

Now, later tests are stopped from running to reduce verbosity, and a
more contributor-friendly error message displayed instead.

We unfortunately can't handle this case in `beforeAll()`, since even
if it throws, later tests in the same file are still run:

docs(contributing): Make the build/test steps clearer (#856)
a359efa 
Previously it wasn't clear that:
* yarn needs to be built before running tests (since the integration
  tests otherwise fail; see also yarnpkg/yarn#6351).
* `yarn watch` can be run even without the first `yarn build`.
* `yarn test` actually runs the linters too.

Also adds a "Setup" section covering prerequisites.
