pipeline: simple: Connect/disconnect frameStart signal at start/stop time
The frameStart signal from the frame start emitter is connected in the
configure() function, and is never disconnected. This means that each
time the camera is configured a new connection is made, causing the
DelayedControls::applyControls() to be called multiple times. Fix it by
connecting and disconnecting the signal when starting and stopping the
camera.
