fix "each" block test run issues

[connectdotz]

Summary

Mainly fix the JestTestRun for the following two scenarios:

1. when running an unresolved test name block, such as jest.each or name as a non-literal string, the tests do not show status after the run.
2. when select "run all tests" for resolved ".each" blocks, the later runs override the earlier, leaving some test blocks marked as "skipped".
