Don't callback on NULL client. Bug 2180510.

We weren't checking to see if there was a valid camera client when
calling the notify callback function. Now we grab a strong pointer
before the callback to guarantee that the client is not destroyed
before we complete the callback. This change also fixes other
places in the code where we weren't holding a local strong pointer.
