Fix a chrome browser crash observed in chrome frame reliability test runs. The crash occurs
when the automation channel is being torn down and a Send on the channel is attempted after
the channel has been closed.
We crash while dereferencing a NULL channel pointer in OnSendMessage task.
Fix is to add a check for the same.
