If a callback with an empty EntityQuery is registered, the registration should be ignored #24

Original report (archived issue) by Shane Loretz (Bitbucket: Shane Loretz, GitHub: sloretz).

Adding an EntityQuery with no component types still leads to the callback being called, but there's no useful work it could do. The QueryRegistrar should return false if an empty EntityQuery is given.

Alternatively, it could return all entities.
