Fixing Few Bugs in Utopian.io

I have worked on fixing two bugs in Utopian.io.

Issue #96 - Bug when navigating to a project page reported by @nathpaiement - Here in this when you navigate to the project page on the first click it does not work and the view remains same however the address bar changes. When you open the console you will get an error like cannot read property 'id' of null.

To fix this issue I need to add an extra parameter when we go through all the contributions as shown below. At first, we were checking if the projectId is present, but we need to check repository id as well.

if (match.params.projectId && contribution.json_metadata.repository.id)

Issue #12 - Search results disappear when scrolling to the bottom as shown below. In the inspect element you can see that we are querying a lot of times

To fix this issue we have to limit the API query to only up-to how many results we have. To fix this I have changed SearchFeed.js file to inlcude the below code

if(this.total !== 0 && this.total <= this.state.skip){
   return;
}

Thus when the total results are less than the querying result, I am returning from there and not going to call the contributions again.
