UTBot fails to generate tests for NumPy

[tyuldashev]

Description
In case function under test uses NumPy function Utbot throws exception and does not generate tests.

To Reproduce

Steps to reproduce the behavior:

import numpy as np

def calc():
    X = np.linspace(start=0, stop=75, num=75, endpoint=True, retstep=False)

1. Create Python project with code shown above
2. Import NumPy if needed
3. Invoke test generation for calc function

Expected behavior

Tests are supposed to be generated.

Actual behavior
No tests are generated, instead exception is thrown.
Even more when test generation invoked again, there is no even exception notification.
