TT#47970 truncate billing_fees_raw in 15424.up

to prevent a pontential foreign key error in susequent

alter table billing_fees_raw
  ..,
  add unique key bfr_srcdestdir_idx (billing_profile_id, type,
match_mode, direction, source, destination),
  ..;

the key is turned into not-unique afterwards with 15449.up
