🐛 Check if embed was edited on end()

[Nico105]

Changes

Added private isEnding property which makes sure that ended is only true if the giveaway embed was successfully edited.

The only thing that isn't checked is wheter all win Messages were sent. But checking that would require too much fetching, so it's not worth it. It's most important that the embed is properly edited.
