Adrian Prantl 737820e6d6 Make diagnostics API safer to use ...

I received a crash report in DiagnosticManager that was caused by a
nullptr diagnostic having been added. The API allows passing in a null
unique_ptr, but all the methods are written assuming that all pointers
a dereferencable. This patch makes it impossible to add a null
diagnostic.
