Use media_id to upload media

[GCorbel]

X recently changed, so we have to use "media_id" instead of "media_key" in requests to upload media.

It fixes #42

[GCorbel]

I copy/pasted the example and had :

> media_category = "tweet_video" # other options include: tweet_image, tweet_gif, dm_image, dm_video, dm_gif, subtitles
=> "tweet_video"

> media = X::MediaUploader.chunked_upload(client:, file_path:, media_category:)
=> 
{"id"=>"1904180809726124032",
...

> media
=> 
{"id"=>"1904180809726124032",
 "media_key"=>"7_1904180809726124032",
 "size"=>2107842,
 "expires_after_secs"=>86400,
 "processing_info"=>{"state"=>"pending", "check_after_secs"=>1}}

> X::MediaUploader.await_processing(client:, media:)
=> 
{"expires_after_secs"=>86392,
 "id"=>"1904180809726124032",
 "media_key"=>"7_1904180809726124032",
 "processing_info"=>{"progress_percent"=>100, "state"=>"succeeded"},
 "size"=>2107842,
 "video"=>{"video_type"=>"video/mp4"}}

> tweet_body = {text: "Posting media from @gem!", media: {media_ids: [media["id"]]}}
=> {:text=>"Posting media from @gem!", :media=>{:media_ids=>["1904180809726124032"]}}

> tweet = client.post("tweets", tweet_body.to_json)
=> 
{"data"=>
...

> tweet
=> 
{"data"=>
  {"edit_history_tweet_ids"=>["1904180958837801012"],
   "id"=>"1904180958837801012",
   "text"=>"Posting media from @gem! https://t.co/Sgui6sMm6U"}}

I don't see how the failing mutant test is related to my changes.

Hey, I made this change myself right before I saw you submitted this pull request. Sorry about that. Version 0.15.1 has been released with this change.

[GCorbel]

No problem but according to the doc, the parameter has to be media_id even for POST requests. I'm surprised that it still works with media_key but we may have the same issue if X decide to change.

@GCorbel Can you re-submit your pull request with all of the conflicts resolved and I'll merge that and release 0.15.2?

[sferik]

@GCorbel Never mind. I was able to pull in all the changes from your branch.
