[CLIENT] Mystery Gift remaining Skin Calculation incorrect

Hello Folks!

Initial Situation So i had a Bug with the Gifting in the Shop. While this might sound like a luxury Problem its still not correct. There seems to be an Bug with the Remaining Skin calculation if you want to gift yourself a Skin - so unselfish i know, i know. If the Account owns all Skins except for 10 (which skins doesnt really matter) the "Gift yourself" function calculates the remaining skins to a Number of 9 while clearly there are 10 Skins left in the Shop.

Steps to Reproduce

1. Get and Account and Own all Skins except for 10
2. Go to the Shop and Gift yourself a Mistery Gift
3. The System will tell you that you cant Gift yourself because there are only 9 Skins left though there are 10 Skins left in the Shop
