ResourceHistogram w/ NonWorkingTime feature changes project default calendar intervals

[arcady-zherdev]

ResourceHistogram w/ NonWorkingTime feature enabled changes project default calendar intervals. The feature adds weekends as non working time.

That code is not supposed to work for SchedulerPro/Gantt dataset it was made for basic Scheduler. The reason is this check in NonWorkingTimeMixin class:

        if (
            // Might have been set up by NonWorkingTime / EventNonWorkingTime already
            !this.autoGeneratedWeekends &&
            // For basic scheduler...
            !client.isSchedulerPro &&
            !client.isGantt &&

Instead of checking view type it should check project type.
