CompleteCode and add_tests

Hello

I am starting you use this plugin, but whenever i try to use `ChatGPTRun add_tests` it only shows around 40 lines and also it seems to be cut

This is some example of the last part of suggestion:
``` res := httptest.NewRecorder()
// Serve the request using the app
app.ServeHTTP(res, req)
// Check that the response status code is 200 OK
if res.Code != http.StatusOK {
t.Errorf("Expected status code

```

CompleteCode just breaks for me.. sometimes it suggest a few things, but mostly blank lines and such

Thanks, really nice plugin

Start by reproducing the issue through the ChatGPTRun add_tests and CompleteCode entry points described in the report, checking whether output is truncated or contains blank lines. Done means both commands return complete, usable suggestions for the reported Go test example; no source file or test path is identified in the issue.
