wb_supervisor_field_get_* can return stale values after wb_supervisor_simuation_reset() if the simulation time is the same as the preceding call.

Describe the Bug
wb_supervisor_field_get_* can return stale values after wb_supervisor_simuation_reset() if the same as the preceding call.

Steps to Reproduce

wb_robot_init();
const int ELAPSED_TIME = 32; // Could be anything
wb_robot_step(ELAPSED_TIME);
double *first_run_translation = wb_supervisor_field_get_sf_vec3f(wb_supervisor_node_get_field(wb_supervisor_node_get_from_def("DEF_OF_SOLID"), "translation"));
wb_supervisor_simuation_reset();
// TODO: Modify something that should change the translation reported
wb_robot_step(ELAPSED_TIME);
double *second_run_translation = wb_supervisor_field_get_sf_vec3f(wb_supervisor_node_get_field(wb_supervisor_node_get_from_def("DEF_OF_SOLID"), "translation"));

Expected behavior
The relevant values in second_run_translation should be different from the values in first_run_translation, but this is not the case, even when they are different in GUI.

System

• Operating System: Linux Fedora Workstation 40.
• Graphics Card: Intel® UHD Graphics 630 (CFL GT2)

Additional context
Using wb_supervisor_node_get_position() works and can be used as a workaround in many cases.

I suspect the problem is triggered by this:

webots/src/controller/c/supervisor.c

Lines 1262 to 1265 in 0a1f1eb

	if (action == GET && f->count == -1 && f->last_update == wb_robot_get_time()) {
	robot_mutex_unlock();
	return;
	}

last_update should presumably be reset on all fields when wb_supervisor_simuation_reset() is called.
