extension_needs_upgrading

Returns TRUE if, for any extension recorded in the object's <code>@extensions</code>
slot whose package is installed, the recorded version stamp is missing (<code>NA</code>)
or older than the installed version of that package. A missing stamp counts
as needing an upgrade so that objects created before extension-version
tracking are brought up to date (and stamped) on first use; this is safe
because <code>runExtensionUpgrades()</code> only calls an upgrade method if one is registered and
such methods are written to be idempotent.
