valid SMARTS with cycles cause error in loader

[AliaksandrDziarkach]

Try to load smarts c:1-2:c(:c:c:c:c:1)-[#6](=[#8])-[#6;X4]-[#6]-2=[#8] using next code

#!/bin/env python3
import os
import sys

sys.path.append(
    os.path.normpath(
        os.path.join(os.path.abspath(__file__), "..", "..", "..", "common")
    )
)
from env_indigo import *

indigo = Indigo()

indigo.loadSmarts("c:1-2:c(:c:c:c:c:1)-[#6](=[#8])-[#6;X4]-[#6]-2=[#8]")

Got next error:

  File "api\tests\integration\tests\formats\smarts.py", line 14, in <module>
    indigo.loadSmarts("c:1-2:c(:c:c:c:c:1)-[#6](=[#8])-[#6;X4]-[#6]-2=[#8]")
  File "C:\Python\Python38\lib\site-packages\indigo\indigo\indigo.py", line 513, in loadSmarts
    IndigoLib.checkResult(
  File "C:\Python\Python38\lib\site-packages\indigo\indigo\indigo_lib.py", line 1003, in checkResult
    raise exception_class(IndigoLib.lib.indigoGetLastError())
indigo.indigo.indigo_exception.IndigoException: array: invalid index -1 (size=12)

Which id wrong.
