Return value of numpy.bincount misidentified as tuple instead of ndarray

[hemberger]

Steps to reproduce

1. Create a file test.py:

"""docstring"""
import numpy
numpy.bincount([1,2,3]).argmax()

2. Run pylint test.py

Current behavior

~ $ pylint test.py
************* Module test
test.py:3:0: E1101: Instance of 'tuple' has no 'argmax' member (no-member)

Expected behavior

No error, because numpy.bincount returns an ndarray (see https://numpy.org/doc/stable/reference/generated/numpy.bincount.html).

pylint --version output

pylint 2.6.1-dev1
astroid 2.4.2
Python 3.7.4 (default, Aug 13 2019, 20:35:49)
[GCC 7.3.0]

(I have tested that this error exists at least as far back as pylint 2.4.2 w/ astroid 2.3.1.)

@hemberger thanks for your report. It sounds like our astroid's numpy brain needs to be be updated.
