Always show an existing directory

When the current directory was deleted otherwhere while in
CollectionFoldersView, a refresh left the user with no choice at all.
Set mCurrentFolder to default (QSetting->folderdir) and say so in the
status bar.

For the latter add a signal to CollectionWidget and connect it to
PlayerWidget::message.
