[PATCH] t/init.t: don't modify ~/.public-inbox/

[Eric Wong]

Tests for failures should not leave junk temporary files lying
around in a users' ~/.public-inbox/.

On a side note, I'm not sure if PI_DIR is or was ever
necessary.  It's never been documented, so perhaps
using $HOME for this is better...
