[VP9] assertion in 1-pass realtime mode when (mis)configured to use altrefs

v1.3.0-2050-g2b06bf2

$ ./vpxenc -y -v hantro_collage_w352h288.yuv \
    -w 352 -h 288 \
    --codec=vp9 --rt --cpu-used=-5 \
    --lag-in-frames=25 --arnr-maxframes=0 \
    -o out.webm
...
vpxenc: ../vp9/encoder/vp9_encodeframe.c:2287: rd_pick_partition: Assertion 
`tp_orig < *tp' failed.

This requires commenting out some vpxenc protections (attached); this is more 
readily reproducible with ffmpeg.
The API should protect against this, it's ok for the application to warn. In 
addition, more API level tests could catch this type of behavior.
