Get and save the workspaceState to the backend

[Zander1983]

Description

• Delete everything from workspace collections (even on production)
• Get the workspace by a request to getWorkspace (instead of using the static WorkspaceState.json file)
• When a user clicks on Plot Sample and chooses a file then:
  - set controlFileId on workspaceState
  - get the first plot - usually SSC v FSC - and save a plot object at files.[the control file id].plots

• save workspaceState to the backend when something changes i.e. on adding a gate, on editing a gate, on changing a channel, on changing a plot type (this should be done just before this.setState())
