Rename getCaptureMotionContainingTimeStamp() -> findCaptureContainingTimeStamp() !...

Discovered an existing findCaptureContainingTimeStamp() !

So all this was done:

• rename
• select most elegant implementation
• make it const (one was const, the other was not)
• comment out the discarded implementation
