Fix camera upload when using both - iPhone and iPad
Photos and videos are synchronised between iPhone and iPad automatically using iCloud Photo Library, so they are stored on both devices (iPhone and iPad). But OneDrive can not identify that files has already been uploaded using one of devices and try to upload the same fales again from another device. Please fix it (look at Google Photos app that has no problem to identify whether photos and videos have already been uploaded of one of devices and if so, app do not try to upload it again).
