[Hub] Cannot manage multiple installations of the same Unity version and launches wrong binary

If the user needs to work with multiple copies of the same Unity version (different builds for example), Hub will be unable to manage this and their work can be launched in the wrong binary which could be potentially destructive and confusing.

Steps to reproduce-
1) Install a recent copy of Unity and open it so that it launches the Hub
2) Install another copy of Unity of the same version as before, but another build version and open it so that I launches the Hub
3) From the Hub, attempt to create a new project with that version
4) Observe that the user cannot manage the multiple versions in the Hub and that it will launch (often) the version that is not intended
