What's Happening

The new `execute on owner` subcommand allows selection of the owner for some entities that have an `Owner` tag (i.e. tamable animals), but not for others (i.e. projectiles).

What Should Happen

The `execute on owner` subcommand should select the owner of any entity that has an `Owner` tag.

Steps to Reproduce

1. Spawn in and tame a wolf.
2. Run the command execute as @e[type=wolf,sort=nearest,limit=1] on owner run me is the owner
3. The chat will display "[Playername] is the owner"
4. Fire an arrow.
5. Run the command execute as @e[type=arrow,sort=nearest,limit=1] on owner run me is the owner
6. The chat will not display anything.
