Python: Fix crash during garbage collection

Same fix as commit d2a5491d1681ead6d8983d0bf6ecae937ab9f317

Prevent Garbage Collector (GC) from deleting host and root objects
before all controller objects under that root/host have been GCed.
This time, it's the init() method that needed the fix. Previously
we had only fixed the connect() method.
