  When receiving a tt_response, we first delete the old entries and
set the initialised flag to false, then add the new received entries,
but forgot to set the initialised flag to true again. This may lead to
endless loops of requests/responses, as a request is always issued
if the initialised flag is not set.

This is a regression introduced by
8ef201e01c57e3bfbcb7f6db69405ff259c2b907.

Fix this by moving initialised = true from tt_update_changes() to
_tt_update_changes().
