Checks: print the General Settings mailing address as the return address

Banking check printing hardcoded companyAddress: undefined, so the association
mailing/office address (accounting.companies.address, set in General Settings)
never printed below the name. Now loads and passes it. Bills check printing
falls back to the company name/address when no company_check_layouts payer is set.
