OAuth: Refactor Token getting and do not save them in the config

This commit refactors getting the tokens into receiver methods. This
means that functions do not have to call the cryptic "EnsureTokens"
method. The receiver getter then already verifier whether or not the
tokens could be obtained (and refreshes too). The downside is that
some things are now private, so testing for invalid tokens needs to be
done somewhere else.

This needs another patch such that clients can save the tokens
themselves using a keyring.
