Junos: get_snmp_information returns blank dict

[doghousedean]

Description of Issue/Question

The output from get_snmp_information is returning a blank dict, looks to be the return from line 1507 in the code is not as expected so the subsequent .items() on line 1509 is not evaluating as True so we get the blank dict from snmp_information from the if on line 1511

I was able to modify the config to add test keys to the dict to confirm it was returning at that point

Other calls work fine, get_facts for example as shown in the details below.

I suspect the problem is around the junos_views yaml file but I'm not sure where to start dissecting it to resolve the issue
