[BUG] No error when trying to parse duplicate keys in plugin config dictionary

[Misaka-ZeroTwo]

When there is a Dictionary<TKey, TValue> for a plugin's config, and you put a duplicate key value in the plugin config file, EXILED will reset the plugin's config without saying anything (no WARN or ERROR messages are printed in console. A backup file is not created, it just wipes it silently.)

Exiled Version: 7.0.0-rc.5

Example:

    OneToOne:
    - original: Scp173
      new: Scp096
      chance: 100
      keep_inventory: true
    OneToOne:
    - original: Scp096
      new: Scp939
      chance: 100
      keep_inventory: true
    OneToOne:
    - original: Scp939
      new: Scp049
      chance: 100
      keep_inventory: true
    OneToOne:
    - original: Scp049
      new: Scp106
      chance: 100
      keep_inventory: true

Ooo, maybe something I can actually do.

Do you want an error message or what?

There should be an error when it happens, and a backup file should be created.

OK. I'll get started on that. Thanks.

That will not solve the issue.

Where is this happening as I'm not sure where to look as everything seems to do the same thing.

Does this occur now?
