Music does not play from the taped position (QMM5)

Issue description:

When a user does seek any position on the progress bar in the Music player app, in some cases music plays from the beginning instead of played back from the tapped position.

What we observed is that the symptom is reproducible in some mp3 files. 

At first, we thought that the issue occurs when there is no duration information in the mp3 file, but found out that there are some cases that the same issue happens even with other mp3 files that the duration information exists in it. 

We didn't have this kind of issue before, but the issue was discovered after removing the webOS plugin and use the QMM5 directly.

We wonder whether it is a known issue, or there is any fix available. 

Note: QMM6 was not tested yet.

How to reproduce:

1. Run QML application which has MediaPlayer object like below.

MediaPlayer

Unknown macro: {                                                                                             id}

2. Seek to any position on the progress bar

3. Play the attached music file.

Expected Result :

1. The progress bar is set to the tapped position.

2. The music plays from the tapped position.

Actual Result:

Music does NOT play from the tapped position, instead, it plays from the beginning.
