buildPursPackage: fix compilation/test execution

Compile all required sources and execute unit tests during the checkPhase.
The `checkPhase` is now a required argument to `buildPursPackage`. It
would be just always execute `npm run test` but this fails in cases
where `spago test` is used which (always) tries to download remote files.
