context: use hex nodeid in error about filtered node
I went a little too far in my cleanup in
9231148ea599 (context:
convert to hex for error message only for 20-byte changeid,
2018-04-06). I missed that the case where a binary nodeid refers to a
filtered node.

A script to generate nasty diff worst-case scenarios:
$ cat > s.py <<EOF
> import random
> for x in range(100000):
> print
> if random.randint(0, 100) >= 50:
> x += 1
> print(hex(x))
> EOF
$ hg init a
$ cd a
Check in a big file:
$ $PYTHON ../s.py > a
$ hg ci -qAm0
Modify it:
$ $PYTHON ../s.py > a
Time a check-in, should never take more than 10 seconds user time:
$ hg ci --time -m1
time: real .* secs .user [0-9][.].* sys .* (re)
