James Ide f68dc80a7c Fix sparse array handling in EventEmitter#listeners() (#24546) ...

Summary:
Fixes a regression in 1f8b46a2fc. The internal subscription vendor uses a sparse array to track listeners, which makes listener removal fast. When querying listeners, the sparse entries need to be removed. `Array#filter` is a built-in way to do this -> linked to the JS spec, which explains this.
