Better errors for invalid manager actions

[daleal]

Right now, when a user tries to use an invalid action on a manager, the error returned is really bad (basically, there is no checking for invalid actions). For example, trying to get an invoice returns the following error:

Traceback (most recent call last):
  File "dist/main.py", line 16, in <module>
    invoice = link.invoices.get("inv_e7Qn499tZ6x14BW3")
  File "/home/epsilon/documents/work/fintoc/fintoc-python/fintoc/utils.py", line 71, in wrapper
    raise error(error_data["error"]) from None
fintoc.errors.InvalidRequestError: invalid_request_error: unrecognized_request
Unrecognized request: GET /v1/invoices/inv_e7Qn499tZ6x14BW3?link_token=link_5Vw1GBZiRaxGpORl_token_4aTYpCwxKRKcAntvHqHe4mTx. Please see https://docs.fintoc.com/ for valid routes.

This might be because the action validation is done through a __getattr__. The SDK should probably work similar to how the Node SDK works (have a method for each action and check on that method).

Is this issue solved?
