Holo subcommands fail to register

Running HoloAPI #447 with Spigot #1591

On enable, I get the following error which interrupts the registration of subcommands.

Error occurred while enabling HoloAPI v2.0.0-SNAPSHOT (Is it up to date?)
com.dsh105.holoapi.libs.command.exception.InvalidCommandException: HoloAPI has attempted to register an invalid command (com.dsh105.holoapi.command.HoloCommand -> debug). Either: Provide a value for "parentCommand" in the annotation, OR add the @Command annotation to the CommandListener class.

As a byproduct of this, existing holograms aren't loaded and cannot be created using the API with another plugin - this throws a RuntimeException because VaultProvider is null.
