  acc: Fix prepared statements for the missed/acc tables

Commit 4bc134fe3b introduced a regression where the reused PS for the
"missed_calls" table (9 fields) would no longer match the PS for the
"acc" table (11 fields).  By reusing the former PS array, which is
shorter than required, the code would segfault.  Example scenario:

    * simple call from A -> B with:
        * do_accounting("db", "missed|failed")
        * call failure (e.g. 408 Request Timeout)
    * code crashes as soon as the "failed" acc entry is written

Many thanks to Nexphone for sponsoring this fix
