Changing ROI via Preview tab does not reset row state

[gemmaguest]

Describe the bug If you manually edit the ROI in the Experiment Settings tab, any processed runs get their state reset (i.e. reset from green to white). However, if you change the ROI via the Apply button on the Preview tab, the state is not reset.

To Reproduce

• Open the ISIS Reflectometry interface and set instrument to INTER
• On the Runs tab enter run number 45455 and angle 1.0. Click Process - the row should turn green.
• On the Preview tab, enter run number 45455 and angle 1.0. Click the Signal button and draw a region on the middle plot. This should perform a reduction and the last plot should update with a line.
• Click the Apply button. Check the Experiment Settings tab and the ROI should have been set in the table.
• Back on the Runs tab, the row's state should have been cleared and returned to white, but it remains green.

Expected behavior The state of any runs that are processed or errored should be reset when the experiment settings are changed.

Platform/Version (please complete the following information):

• Ubuntu 22.04, probably all
• Mantid Version 6.6

I think this could be fixed by calling ExperimentPresenter::notifySettingsChanged() from ExperimentPresenter::notifyPreviewApplyRequested().
