[Bug]: Empty paths cause issues with caching settings. Properly handle empty paths.

Summary:

When the path resolves to "", the stage level cache settings are auto propagated to this endpoint.

Config:

custom:
  apiGatewayCaching:
    enabled: true
    clusterSize: '0.5'
    ttlInSeconds: 600
    perKeyInvalidation:
      requireAuthorization: false

functions:
  blah:
    events:
      - http:
          path: ""
          method: get
      - http:
          path: "/{id}"
          method: get
          caching:
            enabled: true
            cacheKeyParameters:
              - name: request.path.id

On Deploy

Serverless handles the empty paths as meaning root "/".
Serverless succeeds in creating the endpoints on the apigateway stage.
serverless-api-gateway-caching applies the settings and responds with a success.
[outcome] cache is enabled on stage.
[problem] the endpoint cache did not get disabled.

i.e. Even though this endpoint "/" does not have caching enabled, since the plugin silently fails with undefined for the operation, the stage level cache settings are propagated to this specific endpoint.
