 fromString(":foo", null) -> "minecraft:foo"
 fromString("foo", null) -> "minecraft:foo"

 fromString(":Foo", plugin) -> null
 fromString("foo:bar:bazz", plugin) -> null
 fromString("", plugin) -> null
      Parameters:
      string - the string to convert to a NamespacedKey
      defaultNamespace - the default namespace to use if none was supplied. If null, the minecraft namespace (minecraft(String)) will be used
