Console portfolio doesn't work any more

[rushiagr]

Describe the bug
When trying to do a .portfolio() on console object, it fails with

InputException: Missing or empty field `date`

From inspecting request from Console, now looks like 'date' query param, e.g. ?date=2021-09-03, is mandatory now.

Code snippet

from jugaad_trader import Console
c = Console(z)  # z is the logged-in Zerodha() object
c.login()
c.portfolio()

Error
(ipython shell output)

    197             return data["data"]

InputException: Missing or empty field `date`

Fix
Console object's generic_function can be edited to add these two lines:

         def generic_function(**kwargs):
+            if route == "portfolio":
+                kwargs["date"] = datetime.date.today().isoformat()
             return self._get(route, params=kwargs)
         generic_function.__doc__ = docstring
         return generic_function

Hacky, but works!

Additional context
Note that I could only make it work after reverting the commit which broke Console access i.e. c0947e1, part of #23. Related issue #15 .
