Incorrect feedback: Removed orphaned object with primary Array

[hugopeek]

Summary

When running Gitify build, the output doesn't show which orphaned objects are removed if primary key is an array.

Step to reproduce

Delete some random data files of objects that have multiple primary keys and Gitify build.

Observed behavior

So when your config is something like:

    cb_fields:
        class: cbField
        primary:
            - id
            - name

the output will be:

Building cbField from cb_fields/...
- Removed orphaned cbField with primary Array
- Removed orphaned cbField with primary Array
- Removed orphaned cbField with primary Array
- Removed orphaned cbField with primary Array
- Removed orphaned cbField with primary Array

Expected behavior

Correct output should be something like:

Building modPlugin from plugins/...
- Removed orphaned modPlugin with primary Collections
- Removed orphaned modPlugin with primary Ace
- Removed orphaned modPlugin with primary FormIt
- Removed orphaned modPlugin with primary ClientConfig
- Removed orphaned modPlugin with primary ImagePlus
- Removed orphaned modPlugin with primary ContentBlocks

Environment

Gitify 0.12.0
MODX 2.5.8
PHP 7.1

As is being done elsewhere I believe, the primary should be json_encode if it's an array.

Thanks Mark. Will look for that and try to create a PR.
