Use fetched GameProfile for getOfflinePlayer(String)

When getting an OfflinePlayer by name we lookup their UUID and then
use that to fetch the OfflinePlayer. If the player has not played on
this server before the resulting OfflinePlayer will return null for
getName(). As this is unintuitive we now create the OfflinePlayer directly
using the profile we looked up and make OfflinePlayer prefer that data.
