Explicitly disconnect from remaining resources in destructors
Explicitly disconnect from remaining resources in the
ChainedConnected and ClientSessionStanzaChannel destructors, so
the event loop will not call the signal handler methods on a
freed object.
Test-Information:
Repeating the test case of creating a Swift::Client instance,
connecting it and then deleting it after a random time below one
second.
On Mac OS X 10.9.5 running this test case causes two ASAN
heap-use-after-free errors and with this patch the errors are
gone.
