Grouping already grouped workspaces has potentially undesirable behaviour

[John Hill]

If you try to group workspaces which already belong to a group, the workspace pointer is copied to an additional group leaving the original in place.

This means subsequent actions to the workspace, in whichever group affects both.

The desired behaviour may be to create a new copy of the workspace for use in the second group, or to remove the pointer from the original.

Steps to reproduce:

• Load multiple files as a workspace group

• Select a few of the workspaces and group them again

• In the second group, delete the workspaces

• Workspaces in the first group are also deleted.

No one sensible does groups of groups, and we don't currently support this.

If anything I kind of like the way it works now in that it prevents workspaces having the same name containing different data.
