Fix property descriptor queries (#3840)
When the getOwnPropertyDescriptor method was invoked the input property
descriptor was not cleared in every case. This could lead to problems when
the property descriptor is not set/modified by the getOwnPropertyDescriptor
call, resulting in a failure at a later state.

Related to this the Proxy getOwnPropertyDescriptor method incorrectly returned
"undefined" value in a single case.
