Organization & teams create callback handling

[allbto]

Hi @mihaidma

Just a small PR for Udaru.
I had a small issue where calling:

await udaru.organizations.create(organization, { createOnly: true })

would ignore my 2 param { createOnly: true }.

My current working workaround is:

await udaru.organizations.create(organization, { createOnly: true }, true)

to skip the missing callback check.

But I thought I would contribute back to fix this small issue.
Let me know if you have any question.
