Fix potential crash in FrameBuffer::IsCompleteSuperFrame

According to crash reports, crash happens at the line with nothing but
|next_frame->second.frame->is_last_spatial_layer|.

Probably, |frames_| contains entries with empty frame unique_ptr.
This CL adds checks to not dereference those empty pointers.
