scoreboard players tag can result in commands.scoreboard.players.tag.tagError

When running a scoreboard tag command with invalid nbt you get an commands.scoreboard.players.tag.tagError instead of showing the actual error like normal scoreboards commands do

Steps to reproduce:
Run: /scoreboard players tag @p TEST {

This will result in commands.scoreboard.players.tag.tagError

With normal scoreboard commands:
Run: /scoreboard objectives add TEST dummy
Run: /scoreboard players add @a TEST 1 {

This will result in: Could not parse dataTag, reason: Unbalanced brackets: {

Wich is a much better error message!
