Replotting 2D data re-opens all closed and cleared slicers

[jack-rooks]

Describe the bug
Clicking the "Compute/Plot" button in the fit panel for 2D data, using a slicer, closing/clearing the slicer, and clicking "Compute/Plot" again re-opens all previously closed and cleared slicer plots (without the slicer overlay on the 2D plot) as well as producing a 1D circular average plot (even if the circular average was not previously performed).

Clicking the "Compute/Plot" button multiple times without using a slicer does not have this issue.

To Reproduce
Steps to reproduce the behavior:

1. In the model fitter, select a model (cylinder was used), tick the "2D view" box, and press "Compute/Plot"
2. Right click the 2D plot and open a slicer (either directly or through the slicer parameters menu)
3. Close the slicer plot and right click the 2D plot to select the "Clear slicer" option
4. Click "Compute/Plot" in the fit panel
5. Observe reopened plots as well as a new 1D circular average plot

Expected behavior
Cleared and closed slicers do not reappear on replotting 2D data

The opening of the 1D circular average may be related to the sector slicer:

From SectorSlicer.py
new_plot.group_id = "2daverage" + self.data.name
Which indicates the ID for the sector slicer is erroneously the ID for the circular average. I will add this to a branch.
