Add tests to project component to shield against regression

[NickLewanowicz]

Expected Behavior

When pr#6 went through we fixed the re-render issues that caused empty lists to be rendered. We should have some tests to protect against regression of this issue.

Current Behavior

No tests were added with pr#6 but we should add some

Possible Solution

We currently use Jest as a testing framework, we should implement a testing directory for components where we test particular components individually.

Possible Implementation

1. Add a directory in testing for component tests
2. make a file with name related to project.js
3. Implement snapshot tests to make sure the list renders with some data
