message: subscriber: remove the duplicated test 'field_filter_events'
  This removes the test `field_filter_events` in
  `tracing-subscriber/tests/filter.rs` as it appears to be a duplicate of
  `field_filter_events` in `tracing-subscriber/tests/field_filter.rs` (see
  discussion at
  https://github.com/tokio-rs/tracing/pull/711#issuecomment-626365124).
