@storybook/addon-docs: Broken source code with shorthand parameters

[yarastqt]

Describe the bug
I'm use shorthand syntax for parameters and all my stories don't have source code.

To Reproduce
Steps to reproduce the behavior:

1. Define parameters in other place, and use shorthand syntax for export default.
2. Run storybook.
3. See No code available for all stories.

Expected behavior

Property parameters should be extended, for example:

export default {
  title: 'Controls/Button',
  parameters: Object.assig(parameters, {"storySource":{"source":"...","locationsMap":{}}),
}

Code snippets

Minimal code for reproduce:

import React from 'react'

const parameters = {}

export default {
  title: 'Controls/Button',
  parameters,
}

export const Plain = () => (
  <div style={{ height: 60 }}>
    <button>Hello Button</button>
  </div>
)

Code after processing:

export default {parameters: {"storySource":{"source":"...","locationsMap":{}},},
    title: 'Controls/Button',
    parameters,
}

System:

Dependencies:

"@storybook/addon-docs": "5.3.18",

Also if define title too in other place, then locationsMap will be empty and source code will not available too.

That's not currently supported. For now you should declare stuff statically as a workaround.
