Return current time-entry #89
Description
As a user, I want to open the app and see the last time-entry created that has not been clocked-out so I can clock-out it whenever I want.
The endpoint will return a time-entry object using the information provided in the Authorization header (JWT). If not time-entry found a 404 needs to be returned. Bear in mind, the API only allows one active time-entry per user.
Once this endpoint has been implemented please provide all the details to the UI team.
