OnAudioPlacebackPercentage PlaybackPercentage (float) doesn't take into account "Start Time" from Play or FadeIn nodes

PlaybackPercent on the OnAudioPlaybackPercent event does not account for Start Offset from the Play or FadeIn node.

Reported and tested in version 4.25.3 (CL-13942748) and version 4.24.3 (CL-11590370).

1. Download Attached Project.
2. Load TestMap if it hasn't already loaded by default.
3. Press Play.
4. The first time through, you should see printed to the screen a blue piece of text which is the current position of the audio in seconds.
5. After the sound clip has finished, the audio finished event will fire to restart the clip from 1 second in. The text will now be red. The output is the same, but because PlaybackPercent doesn't take into account the 1 second start offset called on play, the current position in seconds can not be correctly calculated.

Results: PlaybackPercent on the OnAudioPlaybackPercent event does not account for Start Offset from the Play or FadeIn node.

Expected: PlaybackPercent should take into account the Start Time value set on Play and FadeIn nodes.
