Another startup bug in 1.3.0-RC2

[Nigel Titley <..hidden..>]

The ./tools/prepare-company-database.sh script produces 

ERROR:  syntax error at or near "entity__get_by_cc"
LINE 1: COMMENT ON entity__get_by_cc (in_control_code text) IS
                   ^
ERROR:  function payment_bulk_post(numeric[], integer, text, numeric,
text, text, date, integer, integer, numeric, text) does not exist

But completes. However it creates a database version 1.2.99 which then
causes 1.3.0 to barf. Altering the database version manually to 1.3.0
allows ledgersmb to start but I get various errors when adding
customers. The customer can be created and the accounts screen can be
run but all the other screens (addresses, contact info, bank accounts
and notes) are blank.
