Bug 25638: Fix float/decimal comparison in API related tests

The previous fix from bug 25513 does not work in all versions we are
supporting.

Let's hack the float/decimal columns in the same way we did for integer.

prove t/db_dependent/api/v1/acquisitions_vendors.t \
      t/db_dependent/api/v1/patrons_accounts.t \
      t/db_dependent/api/v1/acquisitions_orders.t

Note that there is another error on U20 for acquisitions_orders.t
