Re: [PATCH v3 0/2] MR6783: winegstreamer: Fix a memory/resource leak.

[Conor McCarthy (＠cmccarthy)]

While this works, and seems to fix hangs as well as leaks in Killsquad, additional refcount tests show that in Windows streams are created when `Start()` is called, and their references to the source are externally visible, so I will modify this to conform.
