Update frame_context_idx for intra_only/e-frames

Currently, the intra_only/error resilient frame will reuse the
frame_context_idx from the frame coded  before it. If the frame
coded before it is an altref frame, the reused frame_context_idx
will point to the ARF_FRAME slot even if cpi->refresh_alt_ref_frame != 1.
This can lead to an uninitialized entropy context for the frame after
the intra_only/error resilient frame.
