tests (e2e/cli/cache_search): make the test more resilient: the caching is triggered by `li.blog.get`, but it is done in parallel without blocking the command, thus there is a possibility that the data is not yet in cache when the following test is done. A loop with delay is done, to be sure that cache is filled before doing the assertion.
