Pre issue-raising checklist

I have already (please mark the applicable with an x):

• Upgraded to the latest Pact Broker OR
• Checked the CHANGELOG to see if the issue I am about to raise has been fixed
• Created an executable example that demonstrates the issue using either a:
  • Dockerfile
  • Git repository with a Travis or Appveyor (or similar) build

Software versions

• **pact-broker gem version: 1.33.0
• **pact-broker docker version: 2.76.0
• OS: e.g. Ubuntu

Expected behaviour

Github pending status checks need to be overwritten by success/failure on github pull requests

Actual behaviour

Github status checking both pending and success/failure status check for the pull requests

Steps to reproduce

1. Give if have already had pact file generated from consumer , modify the pact file to add a new interaction or change an existing interaction
2. Publish pacts to pact broker which will publish a pending status on the github PR
3. After provider CI is complete, you will see a both status checks on the github PR

Relevant log files

We are not seeing any logs in the pact broker open-source on-premise hosted version
