[fix] utils.js_variable_to_python - partial revert of 156d1eb8c (#5458)

Browse Source 
The JS string, whose encoding will be corrupted if all single quotes (followed
by a comma) are replaced with double quotes. Bug was introduced in PR #4573.

Here is a simple example in which the list get corrupted::

    >>> s = r"""[ 'foo\'', 'bar']"""
    >>> print(s)
    [ 'foo\'', 'bar']
    >>> print(s.replace("',", "\","))
    [ 'foo\'", 'bar']
