Bring login into the axios pattern
on creating a post, first check that we are logged in and try to login again if not

Login will be brought into the Axios pattern by #118

The post check will require slightly more work.

Okay with closing this Issue once the PR is done/merged, and then we can create a new one for checking login is valid before applying the post. I forget the inspiration for that element of this issue

oh, was it a login timeout thing?

There's one more fetch() call that should be migrated to axios- the push token registration in /containers/GlobalDataContainer.js
