Cannot upload PDFs, mp3s, mp4s etc. using the Content Management API. Images work fine.

Issue description

I get a 422 response when trying to upload a PDF

Here's the cURL:

curl --request POST \
  --url https://api.umbraco.io/media \
  --header 'Api-Key: myKey' \
  --header 'Content-Type: multipart/form-data; boundary=---011000010111000001101001' \
  --header 'umb-project-alias: projectAlias' \
  --form 'content={
	"mediaTypeAlias": "File",
	"name": "debug",
	"umbracoFile": "name.pdf"
}' \
  --form 'umbracoFile=@C:\Users\Darek\Desktop\name.pdf'

I've tested this on 2 projects and made a GET call to see what the PDF would return.
Migrated project returns:
"mediaTypeAlias": "File"
New project returns:
"mediaTypeAlias": "umbracoMediaArticle"

That is cause from what I can see none of the migrated projects received the additional media types such as article, audio etc.
Either way, uploading the PDF doesn't work whether I input File or umbracoMediaArticle in the call.

I've also confirmed that the extension .pdf isn't disallowed in the uploadFile field.

It is, however, possible to upload a PDF by using this format:

curl --request POST \
  --url https://api.umbraco.io/media \
  --header 'Api-Key: myKey' \
  --header 'Content-Type: multipart/form-data; boundary=---011000010111000001101001' \
  --header 'umb-project-alias: projectAlias' \
  --form 'content={
	"mediaTypeAlias": "Image",
	"name": "tis a pdf" ,
	"umbracoFile": { "src": "tis-a-pdf.pdf" },
	"umbracoExtension": "pdf"
}' \
  --form 'umbracoFile=@C:\Users\Darek\Desktop\tis-a-pdf.pdf'

The problem with this is that the PDF ends up like this:

Using any of the others media type aliases in the mediaTypeAlias results in the call creating a media container but not uploading the actual file into it like so:

Can verify that it works now after the patch today :)

I can confirm it works for us, too. Thanks!
