version_compare in CRM_Utils_Form::doIncrementalUpgradeFinish() tests unset value

CRM_Utils_Form::doIncrementalUpgradeFinish() does this -

if (version_compare($currentVer, '4.1.alpha1') >= 0)

{ CRM_Core_BAO_Setting::updateSettingsFromMetaData(); }

But it doesn't get $currentVer passed in from CRM_Utils_Form::buildQueue(), so this will only ever print a warning and skip the step.

I'm unclear on whether the updateSettingsFromMetaData() step is required at all.

Small change to buildQueue() can restore the passing in of this value.
