XWikiRightService#hasAccessLevel badly evaluates rights for simple users on sub wikis from the main wiki (under some conditions)

I haven't been able to reproduce locally for the moment but the bug can be reproduced on xwiki.org

$xwiki.xWiki.getRightService().hasAccessLevel("view", "xwiki:XWiki.jvdrean", "dev:Main.WebHome", $context.context)

returns true, xwiki:XWiki.jvdrean has admin rights.

$xwiki.xWiki.getRightService().hasAccessLevel("view", "xwiki:XWiki.XWikiNotifications", "dev:Main.WebHome", $context.context)

returns false even though xwiki:XWiki.XWikiNotifications has view rights on dev:Main.WebHome
