Update IPC message handling for SecurityKeyIpcClient class

Per discussion with DCheng, we should not be DCHECK'ing if we receive
the connection IPC message out of order or when not expected.  This
change will now call the error callback if this situation occurs which
will gracefully close the IPC connection.  I've also added unit tests
for these scenarios.
