(fix): Checking request has parameter before reading them

[dix]

Hi,

The list method of basicRepository allows us not passing any parameter/argument for our request.

But the Client, before performing the request, will check is the request is scape scoped by reading its parameters, using the isSpaceScopedRequest method of SpaceScopedRequest.

This method doesn't check that the parameters are not empty (= command is defined) before trying to access them; which result in a runtime error :

/xxx/node_modules/@octopusdeploy/api-client/dist/spaceScopedRequest.js:5
    return "spaceName" in command;
                       ^
TypeError: Cannot use 'in' operator to search for 'spaceName' in undefined
    at isSpaceScopedRequest (/xxx/node_modules/@octopusdeploy/api-client/dist/spaceScopedRequest.js:5:24)
    at Client.<anonymous> (/xxx/node_modules/@octopusdeploy/api-client/dist/client.js:240:76)

I encountered the issue while calling list without parameters on a SpaceRepository instance ; while trying to retrieve Spaces without any criterion.

The fix proposal is to check that the request do have parameters before accessing them; avoiding a runtime error when there isn't any parameter.
