resync falsely detects changes in Status fields

[glennmatthews]

Environment

• Python version:
• Nautobot version: 1.0.0b3
• nautobot-netbox-importer version: 1.1.0

Expected Behavior

After successfully importing a NetBox data dump, a second re-run of the import process with the same data should report no changes detected.

Observed Behavior

Objects with "status" fields are seen as having changes, e.g.:

  src: NetBox210DiffSync
  dst: NautobotDiffSync
  flags: DiffSyncFlags.SKIP_UNMATCHED_DST
  action: update
  model: site
  unique_id: d25b6c47-2eb1-570e-aee0-8de6b100273d
  diffs: 
    {'+': {'status': {'slug': 'active'}},
     '-': {'status': TaggedForeignKeyField('d29cd273-9e32-4b20-8d65-8f39abac73ad')}}

Steps to Reproduce

1. nautobot-server import_netbox_json dumps/netbox_dump.json 2.10.5
2. nautobot-server import_netbox_json dumps/netbox_dump.json 2.10.5 - again
