Prevent logout GET from getting documented by schema generation

[sloria]

If ACCOUNT_LOGOUT_ON_GET is False, a 405 response is appropriately returned.

However, when using DRF's automatic schema/docs generation, the GET method is still documented.

Conditionally implementing the get method on the LogoutView will prevent the get endpoint from appearing in the schema/docs.

Hi,
as a user of rest-auth, thanks for the contribution!
This repo is not maintained anymore, so the development moved to dj-rest-auth. (reference: #568)
It may be best, if you move this PR there. (and upgrade to using dj_rest_auth)

new repo link: https://github.com/jazzband/dj-rest-auth (I'm not the upkeeper of that repo, it just makes sense for me to help you merge your PR)

Many Thanks,
Barney
