CI/CD/Tests - Test race condition

[elycruz]

There seems to be a race condition in test/index.test.ts, where a particular test fails on fresh installs and sometimes on github CI/CD actions - Subsequent runs of the test causes the test to pass which points to either a race condition or caching issue though requires further investigation:

Test result, from github CI/CD run:
https://github.com/differui/rollup-plugin-sass/runs/3738609952?check_suite_focus=true#logs)

  ...
  index.ts › should support output as function

  test/index.test.ts:170

   169:     .then(rslt => t.true(squash(rslt.toString()) === ''))
   170:     .then(() => t.true(                                  
   171:       outputSpy.calledWith(expectedSpyArg),              

  `outputSpy` should've been called with `body{color:red}body{color:green}`.  Spy called with `body{color:green}body{color:red}`, other args [[{"id":"/home/runner/work/rollup-plugin-sass/rollup-plugin-sass/test/assets/actual_b.scss","content":"body{color:green}"},{"id":"/home/runner/work/rollup-plugin-sass/rollup-plugin-sass/test/assets/actual_a.scss","content":"body{color:red}"}]]

  Value is not `true`:

  false

  › test/index.test.ts:170:23

Acceptance Criteria

• Test should not fail, on first install, and/or on github CI/CD, on subsequent, scenario, runs - 'first run'/github CI/CD dev-build-and-test workflow re-run etc..
