Make loglist buildable again

[Minoru]

Please see this commit's message to get an idea of what's going on here.

I tried to fix CI as well, but something's up with PostgreSQL on Travis. I suggest concentrating on testing with docker-compose for now, here's how:

$ cp devenv.example devenv.your_nickname
$ edit devenv.your_nickname   # Set recaptcha keys
$ source devenv.your_nickname

$ docker-compose up -d
# `loglist_db_1` comes from `docker-compose ps`
$ docker exec -it loglist_db_1 psql --username horta loglist
loglist=# insert into approver(name, email) values('dummy', 'dummy@example.com');

# Test at https://localhost:9000

# After submitting a couple quotes, get approval URLs for them:
loglist=# select 'http://localhost:9000/quote/approve?token=' || token from suggested_quote;
# Click the URLs this prints out.

loglist=# \q
$ docker-compose down

Fixes #223.
