This ensures we do not miss events. E.g.

before:
t0: hash changes to X
t1: send webhook(X), waiting for response
t2: hash changes to Y
t3: queue next webhook(Y) but can't send because previous is not done
t4: crash
t5: restart
t6: find repo at hash Y

no webhook(Y) was sent.

after:
t0: hash changes to X
t1: send webhook(X), waiting for response
t2: hash changes to Y
t3: queue next webhook(Y) but can't send because previous is not done
t4: crash
t5: restart
t6: find repo at hash Y
t7: send webhook(Y), waiting for response

Fixes #313
