MDL-80836 auth_lti: take user through login instead of sesspiggyback
Browsers are phasing out 3rd party cookies. Those which can be set are
partitioned to the top level embedding site, so piggybacking is
prevented. This will break the account linking process. This fix swaps
the piggyback for a login round trip, as originally intended, which
resolves the issue.
