Fix Ivy Failing Test: paddle - general.get_item

This issue might be related to the test suite. It is throwing RuntimeError: (PreconditionNotMet) Tensor not initialized yet when DenseTensor::place() is called. whenever an empty array is passed, for example ivy.array([]). I did some debugging, and found that the error was coming inside the get_ret_and_flattened_np_array function, specifically in the ret = fn(*args, **kwargs) line. Interestingly, when I tried to replicate this error outside of pytest, it did not throw this error.

import paddle
from ivy_tests.test_ivy.helpers.pipeline_helper import BackendHandler

import ivy
from ivy.functional.backends.paddle.general import get_item

backend_to_test = "paddle"
args = [ivy.array([]), ()]
kwargs = {"copy": False}
fn = get_item

with BackendHandler.update_backend(backend_to_test) as ivy_backend:
    with ivy_backend.PreciseMode(False):
        ret = fn(*args, **kwargs)

I'm attaching the output of pytest ivy_tests/test_ivy/test_functional/test_core/test_general.py::test_get_item --verbose --backend paddle:
paddle_get_item.log
