Lipu Fei 834fd055b6 Fix conflict resolve strategies in project loading
CURA-4053

When loading a project file:

- Only check if the global stack exists to detect conflicts instead
  of checking the global stack and the extruder stacks. It can happen
  that the global stack exists while the extruder stacks not or the
  other way around.

- Always assign a resolve strategy to container(s). There can be
  "None" strategies and those were not handled correctly.
