Minor bug fixes

Some performance stuff pushed, as well as a pretty big bug pointed out to me a while ago that prevented people from duplicating players added to their teams. Originally it was done to stop people from adding the same player twice (i.e. Odell Beckham x2) but had the additional affect of preventing people from added multiple of the same draft pick (i.e. 2017 1st). Obviously this is not good, so it’s been fixed.
