NAPALM LLDP neighbors view breaks when LLDP hostname value is null. Where "breaks" means that the Ajax spinning wheel spins forever and the view never returns anything.

For example, when the NAPALM JSON output contains:

    "swp27s1": [
      {
        "hostname": null,
        "port": "Embedded, Port 1"
      }
    ],

This happens with connected hosts that have Intel X710 NICs that do LLDP in firmware. Most people will disable LLDP in firmware for practical use but we will always have servers in a not-yet deployed state that will be like this.

NOTE: There is also likely a bug in the NAPALM driver which is returning "null", but either way, IMO the view should not break because of this.

I will submit an MR to fix this.

Environment

Python version: 3.6.5
NetBox version: 2.4.5

Steps to Reproduce

Setup NAPALM drivers and platform mapping correctly then test w/ LLDP data that has null instead of a string in the hostname.

Expected Behavior

A view should be returned w/ empty hostname data for the port.

Observed Behavior

View stuck forever in spinning wheel.
