[Test] Check skipped unit tests

[ananzh]

Describe the bug

Currently, there are 258 skipped unit tests, 9 todo. We want to investigate whether we can enable the skipped tests. Some of the tests might need to be removed.

Test Suites: 23 skipped, 1411 passed, 1411 of 1434 total
Tests:       258 skipped, 9 todo, 10357 passed, 10624 total
Snapshots:   2363 passed, 2363 total

To Reproduce
Run:
yarn test:jest

Expected behavior
explore each skipped unit test and do the following step for each test suite

1. create a sub issue for each test suite
2. for the skipped unit test, check:

• can we enable it? if yes, create a PR and close the issue

• can we remove it? if yes, create a PR and close the issue

• should we keep it? if yes, describe the reasons in the issue.

The final output is expected to be a cleaned unit test with all the skipped ones being checked.
