WSMAN enumerate fails to return all entries

When querying an enumeration using the WSMAN enumerate method, not all
entries are returned if there are more than max_elems (default of 100)
in the enumeration.

When querying an enumeration, the first response returns <wsman:Items>
in the body.  Successive pulls, however, contain <wsen:Items>.

The old code always queried for <wsen:Items>, which caused the first
batch of attributes to be dropped only when the number of entries in
the enumeration exceeded max_elems.

This patch queries for <wsman:Items> in the first response, and for
<wsen:Items> in successive responses.
