The handlers tests ran one at a time because config.New writes the
global viper instance. Each test spends most of its time in SQLite
under the race detector, so run in a row they took longer than the
20-second target.
Every test and subtest now calls t.Parallel(), as the ircserver and
db tests already do. A mutex in newTestServerWith makes tests start
their servers one at a time, since config.New writes viper and the
server reads it as it starts. No test is removed or otherwise
changed.
