SNMPVariable.oid_index set incorrectly for multi-index variables

[DanielDisisto]

When doing an SNMP get/walk/etc and either the use_numeric flag is True, or if the MIB is not loaded, the .oid_index incorrectly steals the last component of the .oid instead of being left blank as expected.

oid_index_example.py -

from easysnmp.easy import Session

session = Session(hostname='localhost', version=2)

for use_numeric in (False, True):
    session.use_numeric = use_numeric
    var = session.get('.1.3.6.1.2.1.25.3.7.1.1.60.1')
    print(repr(var)))

output -

<SNMPVariable value='1' (oid='hrPartitionIndex', oid_index='60.1', snmp_type='INTEGER')>
<SNMPVariable value='1' (oid='.1.3.6.1.2.1.25.3.7.1.1.60', oid_index='1', snmp_type='INTEGER')>

expected output -

<SNMPVariable value='1' (oid='hrPartitionIndex', oid_index='60.1', snmp_type='INTEGER')>
<SNMPVariable value='1' (oid='.1.3.6.1.2.1.25.3.7.1.1.60.1', oid_index='', snmp_type='INTEGER')>

It appears that easysnmp.helpers.normalize_oid() does the right thing with numeric OIDs, but maybe interface.c is doing something odd?

I haven't used/pulled multi-index variables before. I'll take a look into this when I have time over the next two weeks.
