Connection error upon executing Travis run

[trystant]

When running tests on Travis, the following errors are occurring:

Unhandled rejection SequelizeConnectionRefusedError: connect ECONNREFUSED 127.0.0.1:5432
    at /home/travis/build/trystant/drywall/node_modules/sequelize/lib/dialects/postgres/connection-manager.js:89:20

    at process._tickCallback (node.js:355:17)

While this does not make the tests fail, this is worthy of note.
