Remove sleep when starting tests

This was introduced as, at that time, there was a race when serving pages. However this I couldn't reproduce. I've tried:

for i in `seq 1 100`; do
make acceptance > /dev/null
echo $?
;
done

However, this led to 100 times a 0 being printed. Giving me the idea this has been fixed in the past.

Fixes #31
