Description

Hey, apologies for not first opening an issue, but it's a very small fix.
When debugging an issue in one of my projects I noticed the debug log: VIDEOJS: DEBUG: VHS: PlaylistLoader > m3u8-parser warn for [URL]: undefined.

This is caused by PlaylistLoader#parseManifest_ expecting onwarn to be called with an object that has a message parameter. In manifest.js#parseManifest the onwarn method is sometimes called with a string. It's also called with a message object inside the m3u8 parser.

Specific Changes proposed

We could either change onwarn to always return a string, or return a message object from inside manifest.js#parseManifest.
In this fix I went with the latter as to not break any usage of parseManifest.

Please let me know if anything is unclear, I'll be happy to append the PR.

Is there a way to get this merged without writing additional tests?

The change is extremely simple, and there is no regression as this was untested behaviour before the change.
