As like count is now returned by the extractor, we need to assert a positive
minimum like count, which is close to the actual value, in order to avoid test
failures due to lower like counts than the ones excepted.
SoundCloud broke the workaround used to get a single file from HLS manifests for Opus manifests, but it still works for MP3 ones.
The code has been adapted to prevent an unneeded request (the one to the Opus HLS manifest) and the HLS delivery method is now used for SoundCloud MP3 and Opus streams, plus the progressive one (for tracks which have a progressive stream (MP3) and for the ones which doesn't have one, it is still used by trying to get a progressive stream, using the workaround).
Streams extraction has been also moved to Java 8 Stream's API and the relevant test has been also updated.
* Deprecated Utils#UTF-8; see StandardCharsets
* Added more helpful methods to ``ExtractorAsserts``
* Use parameterized (cool new) tests
* Restore functionality of some tests + updated mockdata
* Other code cleanups + Sonarlint improvements
resolveIdWithEmbedPlayer() does not work anymore because the JSON data has been extracted to an API call. For this reason, replace resolveIdWithEmbedPlayer() with resolveIdWithWidgetApi)( which performs the API call.
The ContentNotSupportedException is thrown because no supported audio streams where extracted. However, SoundCLoud does not check, whether there are any streams available.
This commit should be reverted in #526
Refactor all stream extractor tests to use new base class.
Remove check if upload date is in the past: this does not have to hold true: youtube premieres turn up in search results even though they are in the future
They didn't have the information to calculate another next page url. So now `nextPageUrl` contains a full link with all video ids, and `getPage` takes the first part of the url (containing 15 streams) and produces another `nextPageUrl` with the remaining streams.
Also add a test for this.
