Ndarray construction can't import zero-dimensional numpy arrays

[arogozhnikov]

Description

See example below

Environment info (Required)

Ubuntu 18, python 3.6, pip-installed CPU-only version
MXNet 1.3.0

Minimum reproducible example

mxnet.ndarray.array( numpy.arange(1).reshape([1, 1, 1]) ) # ok
mxnet.ndarray.array( numpy.arange(1).reshape([1, 1]) ) # ok
mxnet.ndarray.array( numpy.arange(1).reshape([1]) ) # ok
mxnet.ndarray.array( numpy.arange(1).reshape([]) )
# last one fails: ValueError: Shape inconsistent: expected () vs got (1,)

MXNet does support zero-dimensional arrays, so this is the problem of importing.
