Fix the audio navigator issue for one-chapter books

[grighakobian]

It's not possible to navigate to the first chapter when an audio book has only one chapter, this small PR will fix for that issue.

Hot to reproduce:

1. Open an audiobook which has only one chapter
2. Play the audio book
3. Try to navigate to the first chapter

Expected result: The audio navigator should start playing from beginning.

Actual result: The player remains on current position, nothing get changed.

Thanks for taking the time to tackle this issue! And sorry about the delay, I was in holidays.

I made some changes, could you take a look and let me know if that's fine with you?

• If a locator doesn't have any locations (not even progression = 0), it would not navigate to the start of the target resource.
• Only notify didJumpTo: if the jump was not interrupted (finished = true)

Also there are build issues in the CI, I'll take a look.

Hi Michel,

Thank you for your changes and sorry for the long delay, I was on vacation 🏝️.

I have checked when the progression is nil the navigator jumps to the start of the target.
