Scope keyword in Security Context is overriden

[flomelki]

Describe the bug
When I use the scope keyword with some valyes within the Security Context, it is overridden with the value ['sql-runner', 'sql-runner-permissions:select,with,explain,analyze,show,check,describe,get,help']

To Reproduce
Steps to reproduce the behavior:

1. Go on the Playground
2. open the Security Context and set { "scope": "test" }
3. display the content of the Security Context through the code (for example with a raise Exception). You should get 'scope': ['sql-runner', 'sql-runner-permissions:select,with,explain,analyze,show,check,describe,get,help'] (with some other values)

Expected behavior
I should get 'scope': ['test'] or possibly 'scope': ['test', 'sql-runner', 'sql-runner-permissions:select,with,explain,analyze,show,check,describe,get,help'] if the other values are mandatory
