Python: Fix crash during garbage collection

Same fix as commit d2a5491 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. Signed-off-by: Martin Belanger <[email protected]>
