[Muon] Seq. fitting: no need to store loaded workspaces

I am storing loaded workspaces for all the seq. fits in the group as well. This is just to get the log values to add to results table.

If I copy the log values from loaded workspace to the '*_Workspace' worskpace when the fit is done, there is no need to do that. This will not only reduce the amount of memory used, but can be handy for users:

Right clicking on the grouped fits from the sequential fitting and selecting 'plot spectrum' produces a lovely graph of all the data. But, of course, the first workspace in the group contains only the data so there's no option for including the fits. Deleting the data (workspaces without an extension) allows data and fits to be plotted by simply right clicking on the group name. I wonder if there's a neater solution. Do we need the data workspaces as the data is also in the '*_Workspace' workspaces?
