Update Test and Build workflow (#648)

- Prevent unintended labels from triggering test workflow
- Prevent pull request from triggering build workflows since test
  workflow would build EDM4U.
- Prevent test workflow from emitting error message just because
  `grep` command did not get any failed tests.
