empty namespaceKey

In the latest update a unique identifier was added to invalidate old cache results, but is missing the key on the initial call.

google-analytics-post-pageviews/google-analytics-post-pageviews.php:466

$namespaceKey = get_transient('gapp-namespace-key');

if ($namespaceKey === false) {
  set_transient('gapp-namespace-key', uniqid(), 86400 * 365);
}

$gaTransName .= '-' . $namespaceKey;

If $namespaceKey is empty and returns false on, then the gaTransName will not correctly be set with the $namespaceKey as it is never updated.

suggested edit:

if ($namespaceKey === false) {
  $namespaceKey = uniqid();
  set_transient('gapp-namespace-key', $namespaceKey, YEAR_IN_SECONDS);
}

sidenote: There’s a time constant for the transients api you can use instead of the numerics for seconds in a year YEAR_IN_SECONDS. Maybe a little more clear about what you’re doing, but not necessary.
