We received a report from an Expert user that is getting hundreds of logs like this, slowing expert down for them:

13:49:57.191 instance_id=1A16BEAE347 [warning] Unhandled trace event: {:compile_env, :elixir, [:dbg_callback], {:ok, {Macro, :dbg, []}}}
13:49:57.191 instance_id=1A16BEAE347 [warning] Unhandled trace event: {:compile_env, :elixir, [:dbg_callback], {:ok, {Macro, :dbg, []}}}
13:49:57.191 instance_id=1A16BEAE347 [warning] Unhandled trace event: {:compile_env, :elixir, [:dbg_callback], {:ok, {Macro, :dbg, []}}}

These seem to come from dbg uses. This PR just ignores that trace event.
