What behaviour is observed:

Whenever a player tries to set it's skin (both restoreSkins option and via command), not only it does not work after the first time it worked (only worked once, the first time the player executed the command) but also prints out an error.

What behaviour is expected:

The expected behaviour is the player to get it's skin updated/changed everytime the setskin command is executed or it joins again to the server (due to restoreSkins enabled).

Steps/models to reproduce:

• Install the plugin in both BungeeCord and Spigot using the same MySQL db
• Set restoreSkin to TRUE or try setting your skin through a command
• It must have worked the first time you used the command, so now leave the server
• Join again and if restoreSkins = TRUE or setskin command executed, it will not work and will print out an error

Extra data:

If I drop the db contents, it will work for once. But then it will just print out an error and it won't work again until I drop the db contents again. And the cycle repeats.
