HPCC-32664 Fix bug creating DFS Group text causing DNS failures

[jakesmith]

The changes introduced in HPCC-18382 (which preserved hostnames), caused group text (via SocketEndpointArray::getText) to be corrupted under certain circumstances.
If the resolved IP of the hostnames in array were sequences, the function encoded it as such, then corrupt the hostnames when deserialized (fromText) was used.
