autocompletion of most recent method is annoying

After executing a method, the next time you type in the object name it autocompletes with the previous method:

```
f = Freesound(577698, {maxvoices:8})
f.note.seq([7,6,5], 1/4)
f.pan = 1

//typing f. here will autocomplete f.pan
```

I can't imagine this is intentional, and would be nice to be fixed
