It shoudl be possible to link multiple OAuth2 sources which have the
same e-mail address to an account.
This patch makes the check for an existing linked account stricter so
that it only checks for linked account records which match the same
issuer, and which do not have expired confirmation tokens.
There were 4 instances of the calendar refresh events task being
queued, which is redundant as we now have the "one true task" to
fix the events table, and it needs to be run for everybody.
This upgrade step was setting the priority field for assign events
in the events table. This is redundant since we queue a task to
refresh all events.
This patch also removes a redundant refresh_events task that is
queued from assign.
The assign update events code depends on the "old" events in the
DB being returned in the same order as they were originally made,
however there was no guarantee that this would be the case.
There were also situations where the priority would not be explicitly
set (e.g., when creating the "original" event).

Previously we did not require the lib.php files for each module
in this ad-hoc task, which meant that the *_refresh_events functions
would only be called if some lucky sequence of events led to the
lib.php file for the module being required.
Instead we should use the component_callback function which can handle
that stuff automagically.
