Summary

Fixes #67365, a regression caused by #59275 introduced in v7.7.0.

Fixes a race condition where the ML plugin would be mounted before receiving its first license information update and thus redirecting to a fallback page (Kibana Home, Space-Chooser or Data Visualizer page depending on the setup).

@jgowdyelastic This should fix the license related race condition we discussed. Now with this code + unit test in place I wonder if we should change the code in a way so we enforce the use of postInitFunction because it's now used both on server and client anyway. We could then maybe even get rid of setLicenseCache because we'll have the initialized license available in the callback and can pass it on as a dependency to the React app. What do you think?

LGTM
Yes I agree that we could now pass the mlLicense to the App now rather than caching it.
This would be similar to the dependency cache removal work that is needed.

Tested locally and LGTM (despite many attempts wasn't able to reproduce the original issue locally. I was only ever able to reproduce on cloud).
