Seconds missing from duration when one hour or longer

[PanderMusubi]

When a media file is long than one hour, the seconds of the duration are not show, which is misleading as they are shown when the duration is less than one hour.

Examples of duration are:

• 1 h 13 min
• 1 h 0 min
• 56 min 21 s

Improved would be:

• 1 h 13 min 0 s
• 1 h 0 min 34 s
• 56 min 21 s
