What is the current behavior?

Currently the scope is being altered by the toCamelCase helper method. This creates the issue that if you provide a scope where you would like to have the first character not to be changed OR just the casing in general you can only do this by providing an alias.

e.g { scope: 'FOOBAR', alias: 'FOOBAR' }

Issue Number: N/A

What is the new behavior?

This feature enabled the possibility to only provide the scope and the casing of it will not be altered, so you can just use this: { scope: 'FOOBAR' } or { scope: 'F-OO-BaR' } --> will be transformed to { scope: 'FOOBaR' }`
