Generating of description for entities in combination of `json` and `write to file` is broken

[Drakorgaur]

Problem definition

In an attempt to create a description of an operator, account, or user using the nsc tool with the output in JSON format and writing the output to a file via the --output-file flag, the tool returns an error.

Steps to reproduce:

• set up nsc(set env vars, prepare space, etc)
• create operator(account, user optional)
• run nsc describe operator -J --output-file $(pwd)/test.json

Expected behaviour:

Stdout:

[ OK ] wrote operator description to `~/<omitted>/test.json`

Real behaviour:

Stdout:

Error: expected 3 chunks

Problem explaination

When cmd.Json is set, Load method sets raw attribute as JSON-bytes

func (p *DescribeUserParams) Load(ctx ActionCtx) error {
  . . .
  p.raw, err = bodyAsJson(p.raw)
  . . . 
}

after this in Run method tries to decode JWT:

func (p *DescribeUserParams) Run(ctx ActionCtx) (store.Status, error) {
  . . . 
  p.raw, err = jwt.DecorateJWT(string(p.raw))
  . . . 
}

which expects bytes be separated by dot, but it's already decoded to JSON.
