Playground code output does not show options if the only option has the value of boolean

[jesperorb]

Describe the bug

Playground code output does not show options if the only option has the value of boolean and that value is false.

The option only show up if you have selected another option in combination with a value that is a boolean. Giving the impression that the option has not been applied but it has in fact been applied but the output does not reflect it.

To Reproduce
Steps to reproduce the behavior:

1. Go to Playground Page
2. Select a Method with a boolean toggle value such as "Collator"
3. Set a boolean value to false while all other options are undefined.
4. Look at code output

Expected behavior
The output should display options for the value like following:

"key": false

Actual behavior

The output does not change in the code output.
