Started work on validator

fix on senschaJSON
improved _id checker
errorHandler first implementation
_id not found validation/errorHandling working

Replaced rawBody with express.json()
added 'message' to senschaJSON
Custom Validation removed, used all in Mongoose
Added comments, refactored tests
Validation done - tests working again
POST _id gets removed, PUT _id does not
