On submission, request payload may provoke some parsing errors

[Akhilian]

To reproduce the problem, send a request with:

Headers:

• Authorization: Bearer <VALID_TOKEN>
• Content-Type: application/json

form-data:

• name: "TEST"

It should provoke:
SyntaxError: Unexpected token - <br> &nbsp; &nbsp;at parse (/Users/Adrien/Projects/OnMyTravel/api/node_modules/body-parser/lib/types/json.js:83:15) <br> &nbsp; &nbsp;at /Users/Adrien/Projects/OnMyTravel/api/node_modules/body-parser/lib/read.js:116:18 <br> &nbsp; &nbsp;at invokeCallback (/Users/Adrien/Projects/OnMyTravel/api/node_modules/raw-body/index.js:262:16) <br> &nbsp; &nbsp;at done (/Users/Adrien/Projects/OnMyTravel/api/node_modules/raw-body/index.js:251:7) <br> &nbsp; &nbsp;at IncomingMessage.onEnd (/Users/Adrien/Projects/OnMyTravel/api/node_modules/raw-body/index.js:307:7) <br> &nbsp; &nbsp;at emitNone (events.js:86:13) <br> &nbsp; &nbsp;at IncomingMessage.emit (events.js:185:7) <br> &nbsp; &nbsp;at endReadableNT (_stream_readable.js:974:12) <br> &nbsp; &nbsp;at _combinedTickCallback (internal/process/next_tick.js:74:11) <br> &nbsp; &nbsp;at process._tickCallback (internal/process/next_tick.js:98:9)
