test: improve coverage (#231)

* feat(ntex-glommio): remove unused mut

* test(ntex-io): check Debug implementation for FilterServiceFactory

* chore: format code

* feat(ntex-util): check Debug and poll_ready for KeepAlive

* test(ntex-util): wait a bit until the poll is ready

* test(ntex-bytes): assert error for implementation try_from for BytesVec

* feat(ntex-tokio): remove unused mut

* feat(ntex-tls): use add_trust_anchors instead of add_server_trust_anchors

* chore: format code

* feat(ntex-util): check readiness after sleeping but before expiring

* feat(ntex-util): remove unnecessary assertion
