fix: Incorrect stop reason

Respect redirect URLs when seeking content

When we play content with StreamingKit most of the URLs are redirected. Servers can do this in order to attach sessionIDs or other parameters to the end of the URL so the seeking can be monitored as one session.

Currently what is happening is when we request to play URL_A and if that is redirected (302 HTTP Status with Location parameter) to URL_B, after a seeking we still try to seek on URL_A losing the session identifier.

Once a URL has been redirected any seeking should happen on the redirected URL.

This release fixes the quality and seeking issues that were associated with M4A contents.
