Fix python coverage database bug with access to database directory

[tamarinvs19]

Description

Fix bug with database path in python module coverage. Now we create database in temporary directory with other python files.

Note: See #1542

Fixes #1478

Type of Change

• Bug fix (non-breaking change which fixes an issue)

How Has This Been Tested?

Manual Scenario

See #1478 steps 1-8 with plugin from this build

Expected result: generated tests, for example:

import sys
sys.path.append('..')
import builtins
import types
import sample
import unittest


class TestTopLevelFunctions(unittest.TestCase):
    # region Test suites for executable sample.print_hi
    
    # region
    
    def test_print_hi(self):
        actual = sample.print_hi((1 << 100))
        
        self.assertEqual(None, actual)
    
    def test_print_hi_throws_t(self):
        sample.print_hi(str(b'\xf0\xa3\x91\x96', 'utf-8'))
        
        # raises builtins.UnicodeEncodeError
    # endregion
    
    # endregion
    
    # region Test suites for executable sample.div
    
    # region
    
    def test_div(self):
        actual = sample.div(1, 1)
        
        self.assertEqual(1.0, actual)
    # endregion
    
    # endregion

Unfortunately it still doesn't work, it looks the same as before - just hangs during generation. It seems that this version has no verbose logging, so I'm not sure if it's the same error (problem with sql-light db file) or another one.
