Bump youtube-dl version to 2019.04.24

[cgtobi]

Description:

media_extractor is currently broken due to YouTube backend changes. There was a youtube-dl update released yesterday that resolves this issue, so the version included in HA needs to be updated to 2019.04.24 otherwise YouTube videos will fail.

Thanks @SeanPM5
