[xml] [PATCH 2/2] uri: don't force double slashes with rootless paths

[Martin Kletzander <mkletzan redhat com>]

This changes xmlSaveUri()'s behaviour for two particular URI types,
below is the difference when $uri is processed with
xmlSaveUri(xmlParseURI($uri)):

Before:
  "scheme:noserver"    -> scheme:/noserver"
  "scheme:/noserver"   -> scheme:/noserver"
After:
  "scheme:noserver"    -> scheme:noserver"
  "scheme:/noserver"   -> scheme:///noserver"
