Merge actor_mesh field to actor_name (#1940)

Summary:
Pull Request resolved: #1940

`actor mesh name` is the same as the `actor name`. This diff removes the `actor_mesh` column, and only use `actor_name`. In this way, we can search scuba with 1 column and get all the logs related to an actor mesh.
