All OAuth Tokens Are Deleted When An Integration Is Deleted

[gary287]

When multiple integrations are defined and one is deleted, all tokens are deleted from the oauth_token table. The expected behavior is that the token associated with the integration that was deleted will be deleted. The current behavior is that all tokens for all integrations are deleted.
