context: optimize _parents()

This patch avoids some extra attribute lookups and list mutations.

This micro-optimization seems to result in a minor speedup for `hg log`
on my Firefox repo:

before: 25.35s
after:  24.91s
delta:  -0.44s (98% of original)

Not the biggest gain. But every little bit helps.
