[local-notifications] update visible notification

## Feature Request

### Plugin
local-notifications

### Description
I'm trying to create an ongoing notification that can be updated without being replaced (a simple timer). Currently when scheduling a notification with the same ID, LocalNotificationManager -> schedule -> dismissVisibleNotification is called causing the notification to be replaced each time. Simply commenting out the line `dismissVisibleNotification(id)` achieves the desired result as android will not replace the notification only update it.

### Platform(s)
Android

### Preferred Solution
Add something to the ScheduleOptions/LocalNotificationSchema to make it optional

### Alternatives
Remove dismissVisibleNotification(id) ? I'm sure this will have side effects that I'm not aware of.
