KeepOpen is improperly handled in the generated code.

[AraHaan]

Issue Details

Currently the generated code should dispose the underlying disposables only when the keep open property is false, however the generated code ends up doing it when it's true instead.

Describe the bug
Currently the generated code should dispose the underlying disposables only when the keep open property is false, however the generated code ends up doing it when it's true instead.

To Reproduce
There is not much to reproducing it if the type is a stream.

Expected behavior
For the underlying streams inside of a stream to be disposed when instructing the stream to not keep it open (not when it is instructed to keep it open).

Actual behavior
It disposes of the underlying stream at the wrong time.
