no index.js exists in tsfn-test, and tsfn_object_wrap.js never exists…

[UrielCh]

no index.js exists in tsfn-test that cause an error in the main test file.

a tsfn_object_wrap.js exists, but do not exist.

by adding a script named loopscript, the test script is still available via a npm run and do not cause an error to the main test script.
