Are you sure you have a wiki named "XWiki"? The main wiki is called by
default "xwiki" (lower case). Anyway, you should avoid hard-coding the
name of the main wiki. You should write instead:
context.getMainXWiki() --> for main wiki or,
context.getDatabase() --> for current wiki.

The above 5 lines are equivalent to this:
DocumentReference refGroup = new
DocumentReference(context.getDatabase(), "XWiki", groupName);
DocumentReference refRights = new
DocumentReference(context.getDatabase(), spaceName, "XWikiRights");

I see 2 mistakes here:
(1) You assume that space level rights are saved on the group document.
You should edit the group document using the object editor and see what
objects it has attached. XWikiRights objects don't have any information
about the target entity (page/space/wiki) because the target entity is
determined based on the document where XWikiRights objects are attached.
So for space rights you should look at the objects attached to
<SpaceName>.WebPreferences page.
(2) In order to retrieve an object from a document you need the class
name/reference, which is the same no matter where the objects are
attached. The class reference fro XWikiRights is xwiki:XWiki.XWikiRights
not xwiki:<SpaceName>.XWikiRights . Now, if I go to the space
administration and edit the user/group rights I get
XWiki.XWikiGlobalRights objects attached to <SpaceName>.WebPreference so
you should use this class instead of XWikiRights.
I would start with this code (which I haven't tested):
----------8<----------
DocumentReference rightsClassRef = new
DocumentReference(context.getMainWiki(), "XWiki", "XWikiGlobalRights");
DocumentReference spacePrefsRef = new
DocumentReference(context.getDatabase(), spaceName, "WebPreferences");
// Get the space preferences page, where space level rights are saved.
XWikiDocument spacePrefs = context.getWiki().getDocument(spacePrefsRef,
context);
// Get the XWikiGlobalRights from the space preferences page.
BaseObject spaceRights = spacePrefs.getXObject(rightsClassRef);
// Modify space rights.
spaceRights.set("levels", rights, context);
spaceRights.set("groups", groupName, context);
context.getWiki().saveDocument(spacePrefs, context);
---------->8----------
Hope this helps,
