Revert "Fix Coverity dereference before null check issue (#13456)"

[julianmi]

This reverts commit c02f915d42ac9bd1a3c4f2215d703b49b3a2173d since this Coverity issue is a false positive. EventImpl is always set when we pass it in the runtime, but the previous change suggests it might be null. The Coverity hit should be ignored instead.
