Driver: Fix crash on .leave() (#63)

Browse Source 
Leaving (rather than removing) a call would cause the driver to crash as it would try to use a non-existent connection immediately after it had been invalidated.

This has been tested using a modified `examples/serenity/voice_storage`, felyne, and via `cargo make ready`.
