clip.clear() TypeErrors

Talon v0.1.2-55-g3026bf9 (55)

Ubuntu 20.04.1 LTS

**To reproduce:** open talon repl, run `clip.clear()` or `actions.clip.clear()`:

```
>>> clip.clear()
Traceback (most recent call last):
  File "<console>", line 1, in <module>
  File "talon/clip.py", line 79, in clear
TypeError: 'void(*)(uint32_t)' expects 1 arguments, got 0
```

also occurs if you use clip.clear() in talonscript.
