Fix recreation of DefaultShaderProgram in FinalWrapper

`outputSurfaceInfoChanged` is not reset when `defaultShaderProgram` is null.
That is, on the first time `ensureConfigured()` is called with output size
changed, `outputSurfaceInfoChanged` is not set to false after creating the
`defaultShaderProgram`, and `defaultShaderProgram` will be created again on the
second time `ensureConfigured()` is called.
