BF: Add default duration to eyetracker record component

[RebeccaHirst]

Eyetracker Record component needs duration in order to stop - so adding a duration value by default so users do not get confused why the experiment halts at the stop record.

I think this is also fixed by #6567 - which adds a "stop with Routine" parameter. But having a default stop time doesn't conflict so happy for both to happen (just trying to get tests passing on the other one)

Sorry @RebeccaHirst @TEParsons: This PR is already merged so my comment might be too late. But I don't know if the change here actually has the intended effect. Isn't the default duration of the EyetrackerRecordComponent already set to be 1.0s by the stopType='duration (s)', stopVal=1.0 arguments? I thought the durationEstim parameter is only used for visual display on the timeline as commented here. So does the experiment actually halt when durationEstim is not set? If so I'm worried that there's another bug somewhere that isn't due to durationEstim.

Ah, I didn't realise - I thought you'd added a default for duration. Yes, duration estim is (or at least, should) only be used in the UI, the experiment shouldn't be affected

Might make sense to revert so that users are not confused by why estimated duration defaults to 1s. But more importantly does the experiment actually halt when EyetrackerRecordComponent stops eyetracking recording? That's what I'm worrying about...

The only thing I can think is maybe it's leading to the routine being marked as non-slip falsely? Will investigate on Monday
