Title: Update module/ShiftBundle/src/Controller/ShiftController.php

Show an error when the date is not valid, avoid fatal errors when some random text is sent instead of a valid formatted date.
```
Fatal error: Call to a member function setTime() on a non-object in /var/www/vhosts/vtk.be/www/public_html/module/ShiftBundle/src/Controller/ShiftController.php on line 122
