ZF-9438: getDateTimeAttribute Null Check
I'm creating a ActiveDirectory extension to the LDAP classes and noticed this bug. In the Zend_Ldap_Attribute class there is a method getDateTimeAttribute(). If the value returned by getAttribute() is an array it should work fine but if it's a single value (specified by the index) then the method doesn't check if _valueFromLdapDateTime() returned null.
Basically, just need to add a check for "non" array attributes that if valueFromLdapDateTime() returns null to return the _original value and not null.
