j3k0 opened a new issue #124: `then` and `catch` both called
URL: https://github.com/apache/couchdb-nano/issues/124
 
 
   ## Expected Behavior
   
    * When using promises ;
    * When `db.get` returns 404 (because the document is missing) ;
    * Then I expect **either of** `.then` or `.catch` callback to be called.
   
   ## Current Behavior
   
    * When using promises ;
    * When `db.get` returns 404 (because the document is missing) ;
    * Then **both** `.then` and `.catch` callbacks are called.
   
   ## Steps to Reproduce (for bugs)
   
   
   ```js
   const rnd = Math.random();
   db.get(id)
   .then((body) => console.log({rnd, body}))
   .catch(err) => console.log({rnd, err}));
   ```
   
   Output:
   ```
   {
      rnd: 0.9767401252511854,
      err: { Error: missing
   at Request._callback (/node_modules/nano/lib/nano.js:151:15)
   at Request.self.callback (/node_modules/request/request.js:185:22)
   [...],
   name: 'Error',
   error: 'not_found',
   reason: 'missing',
   scope: 'couch',
   statusCode: 404,
   [...]
      }
   }
   
   {
     rnd: 0.9767401252511854,
     body: undefined
   }
   ```
   
   ## Context
   
   Check if a document is already in the database.
   
   ## Your Environment
   
   Node v10 on Docker (image `node:10`).
