In live situations, it is not uncommon for the current fragment to end up out of the (updated) play range (lowest/highest sequence). But the next fragment to play *is* present in the play range. When advancing, if we can't find the current GstM3U8MediaFile, don't abort straight away. Instead, look if a GstM3U8MediaFile with the next sequence value is present, and if so switch to it. https://bugzilla.gnome.org/show_bug.cgi?id=750028
