The "commands.test.success" raw translation key is displayed when using "/test create..." command

The Bug:

2. Enter the following command:
/test create minecraft:always_pass
3. Observe what message is displayed in chat.

Observed Behavior:

The "commands.test.success" raw translation key is displayed.

The translation key “commands.test.create.success” is used.
