Keep errors after fit in BaselineModelling step

Allow algorithm dialog boxes to stay open

The change removed those weird visual artefact. Issue is thus closed.

This generated a warnging not an error. Added a hint in the maintenance
ticket #12925 to fix this.

The new algorithms can save and load offset, mask and group workspaces as designed.  The only issue found is that the instrument of the original mask workspace and the one of saved-loaded mask workspace are not same.  I point it out though I think it is another issue to mask workspace.  Issue is thus closed. 

Fix PreviewPlot showing multiple error bar options for same curve

Workspace is polymorphic, so in general we do not want any public copy
or assignment. In some cases this required moving the user defined copy
constructor out of the public area, in other cases it meant adding it in
the protected section, to avoid auto-generation by the compiler.

Note that we make the copy constructor protected and not private. This
is in view of the upcoming introduction of a clone() method, which will
need to call the copy constructor of the base class.
