Playing info won't change when playing music after queue ended

[mkaraki]

• Can change correctly when Playback Queue isn't displayed

  • Also, this makes it safe to use queue direct selection after this operation.

• Can't change if Queue is displayed (and it will break both Skip button and queue selection.)

• After the problem occurs, All the changes about playing info won't work (even if it has queue reset).

• This works in 2fec517 in another environment (may be changes fault or loading speed problem)
