Local files still shows as unavailable (grey) songs in albums

[paulodiovani]

If I have local files they become always available to play or add to playlists. But if I access the album songs still shows as unavailable (grey).

This looks very weird, cause:

- Songs are greyed

- No play icon is shown on the left on hover

- Song still can be played with a double click

- Song still can be favorited or added in a playlist

- Song is synced with other devices and can be played elsewhere (tested with mobile phone, only)
