Small typo in README

Under https://github.com/torchbox/wagtail-wordpress-import#first-steps-to-configure-your-wagtail-app

It's intended that these fields are temporary for while importing, and can be removed once the content has been imported.

Maybe should read:

That would change the meaning to be wrong. The fields are temporary. The fields are for use while importing. They don't become permanent when you have finished importing. Therefore although it is not false to say that they are "temporary while importing", it is similar to saying that "seatbelts are provided when you are in a crashing car", rather than that they are always provided for when you are in a crashing car.

Perhaps the message isn't clear. What wording would make this clearer?
