TET-admin: Editor unit test fails randomly

[sirtawast]

We've identified a flaky unit test on TET-admin. Sometimes test just fails for no reason. In today's monorepo check we came to conclusion that it's better to continue pushing shared content than to wait for this to be patched properly.

This test will pass on localhost.
