SLS logs --tail broken on google-nodejs template

Bug Report

Description

1. What did you do? I've deployed a very simple function to GCP that logs upon topic publish. When publishing a topic I'm able to see the console.log statement in the logs. When adding the -t or --tail argument however, the tail does not hold and simply acts as it would without the tail.
2. What happened? It ignored the tail flag
3. What should've happened? It should have tailed the log stream
4. What's the content of your serverless.yml file?

service: cloud-functions

provider:
  name: google
  stage: dev
  runtime: nodejs10
  region: us-east1
  project: cloud-functionsxxxxx
  # The GCF credentials can be a little tricky to set up. Luckily we've documented this for you here:
  # https://serverless.com/framework/docs/providers/google/guide/credentials/
  #
  # the path to the credentials file needs to be absolute
  credentials: ~/.gcloud/cloud-functionsxxxxx-serverless-key.json

plugins:
  - serverless-google-cloudfunctions

# needs more granular excluding in production as only the serverless provider npm
# package should be excluded (and not the whole node_modules directory)
package:
  exclude:
    - node_modules/**
    - tooling/**
    - .gitignore
    - .git/**

functions:
  sendSlackNotification:
    handler: sendSlackNotification
    events:
      - event:
          eventType: providers/cloud.pubsub/eventTypes/topic.publish
          resource: 'projects/${self:provider.project, ""}/topics/sendSlackNotification'

1. What's the output you get when you use the SLS_DEBUG=* environment variable (e.g. SLS_DEBUG=* serverless deploy)

$ SLS_DEBUG=* sls logs --function sendSlackNotification --tail
