** Screenshots **

Expected behavior

Changing my package.json file to angularefire2 to 5.0.0 version and doing npm install, whereas my Typescript version is 2.9.2, shows a warning that no package was installed because angularfire2 is ok with
typescript >= 2.7.2 & < 2.8.0.

Actual behavior

I have an app that runs with Typescript 2.9.2 and angularfire 5.0.0-rc.11 and that works fine. I installed first angularfire2, then upgraded my typescript version. The app is ok. The problem is when I try to upgrade to version 5.0.0.
