Backend doesn't log on console

[mesudip]

What

Backend doesn't log anything on console except listening on Host "0.0.0.0":8080. Sentry is the only way to find out error messages when they occur. This is true even when sentry configuration is omitted.

Acceptance Criteria

• Govtool backend logs errors to console when they occur.
• When SENTRY_DSN env variable is not set on backend, sentry is not initialized.
