erp5_configurator_standard_solver: Add missing solver_workflow to Quantity Split Move Solver
The missing workflow resulted in a bug when moving quantities multiple times, first to one delivery, then to another delivery. Then the same solver process with same decision was used as for the first time even if the first delivery was already delivered or movement was deleted. The reason was that Quantity Split Move Solver did not change to succeeded state after solving, so Solver Process did not change to solved state.
TODO:
- Pick and adpat project-specific test to reproduce in generic erp5
