GUI/SYNOPTIC: Edit copies of components macros

As a user, I want to edit the component macros of copies of components when creating a synoptic.

• Currently editing any copy changes the component macros of all components which have been copied.
• Changing the name of copies changes only the name of that component - not any copies.
• You can edit the component macros of copies after saving the synoptic without changing the other copies.

Steps to duplicate:

1. Create a component.
2. Copy that component.
3. Change the copied component macro.
4. The original component macro has changed to be the same as the copied component macro.

Found while creating synopitcs for TOSCA as part of #3444.

This needs to be fixed by the training sessions.
