jdlrobson eea19f3e18 PageIssues should use new standard pageToken getter
Rather than inventing its own page token the PageIssues
schema will rely on the standard page token.

In future when I9bb18d47e36d2d99d812e5b47ea9516d3dff3a16 is
merged this will mean that PageIssues and ReadingDepth have
consistent page tokens.
