[dlaweb]

Describe the bug

Something is broken since the last release 0.5.0; tasks aren't executed anymore in that specific case :

To Reproduce

package main

import(
	"fmt"
	"time"
	"github.com/go-co-op/gocron"
)

func task() {
	fmt.Println("Im a dummy task")
}
func main() {
	// defines a new scheduler that schedules and runs jobs
	scheduler := gocron.NewScheduler(time.UTC)

	j, _ := scheduler.Every(1).StartAt(time.Now().Add(5*time.Second)).Do(task)
	j.LimitRunsTo(1)
	scheduler.StartAsync()
	
	time.Sleep(15*time.Second)

}
