Missing usage translation for '/advancement test' command

When executing the command "/advancement test", a proper usage message is supposed to appear, however this appears:

Usage: commands.advancement.test.usage

instead of the expected translation, which is not included in the 17w13a JAR file inside en_us.lang

Steps to reproduce:

• Start a world with Gamemode creative in the client version of Minecraft 17w13a
• Ensure that no resource packs are enabled
• Enter the command /advancement test
