Fix 2x-nested translation of record list fields (#1)

For bet365/soap#47

When using `soap:erlang2wsdl` on the referenced `.hrl`, a crash occurs
as described in the above issue. This is because the nesting of the
translated `hobbies` field is doubled up; the return value from
`erlsom_type2xsd:translateType/2` has the `MinOccurs`/`MaxOccurs`
wrapper applied twice for lists.

Ignore the list element type's `MinOccurs`/`MaxOccurs` and use the 0 and
unbounded values, for lists, respectively. This will produce the same
result as shown on https://github.com/bet365/soap/blob/6848d29d9d123c37f22b309f19de848f6309b66a/doc/generating_a_wsdl.md?plain=1#L160.
