just a temporary solution to show the conference fee in the foreign trip
report, which was not shown at all. there is still a mixup with the name
of identifiers allowance_ and advance_fee, need to fix later after
we get info about allowance from mrs. secretary.
currently, the user does not specify allowance in the form at all,
which is strange, but it might be ok, if everybody just refuses it automatically.
just need to double-check. but then the allowance identifier in the DB/model
is a wrong name, and need to rename this...
