Add tests for capture console integration

https://github.com/getsentry/sentry-javascript/blob/master/packages/integrations/src/captureconsole.ts

@AbhiPrasad you think we can close this now or do we want to keep it open until we have integration tests?

[AbhiPrasad]

I think we are good to close this
