We want to wrap the `Ember.run.debounce` function and internally call `Ember.run` instead when running tests.
This commit changes discourseDebounce to work the same way as `Ember.run.debounce`.
Now that `discourseDebounce` works exactly like `Ember.run.debounce`, let's replace it and only use `DiscourseDebounce` from now on.
Move debounce to discourse-common to be able to reuse it in different bundles
Keep old debounce file for backwards-compatibility
Meta report: https://meta.discourse.org/t/sending-many-requests-for-video-audio-upload-while-editing-post/161487
When typing in the composer we are sending a lot of unnecessary load() requests for the video/audio elements. This line was added months ago before we improved previewing/video thumbnails, which have improved things, so it is no longer required. After removing this line everything still works and no more additional requests are sent.
This fixes an issue where sometimes when composing a post and uploading a video/audio file, _loadCachedShortUrls/the uploads controller would return a full URL with origin, instead of just the URL with the host e.g. http://localhost:3000/some/video.mp4 instead of just //localhost:3000/some/video.mp4. We were prepending window.location.origin onto the URL no matter what, and since http://localhost:3000/some/video.mp4 does not match the host URL regex, we were ending up with something like http://localhost:3000http://localhost:3000/some/video.mp4 which broke composer previews. This was only noticed with a video upload in a secure upload environment.
- This function now requires an explicit scope. It will never run on the entire document.
- Previously debounce was being used with an anonymous function, which means it was having no effect.
