The user running the migration might not have superuser permissions.
Using IF NOT EXISTS allows a root user to install the extension
manually, and then the migration will succeed as an unprivileged user.

It isn't solved yet, but once we've committed to v1 of the archiving
service we won't want to edit V1__init.sql ever again to avoid changing
its checksum (Flyway complains if the checksum changes).

I'm going to try to minimise use of this (as per
https://github.com/google/guice/wiki/Avoid-Injecting-Closable-Resources).
For example, I'm going to inject a pooling DataSource rather than
Connection objects, as per the advice at the end of the page. However,
HikariCP's DataSource implementation is itself Closeable.

The previous code included too many rows as the use of LEFT JOINs meant
candidate group orws with an incorrect container_id were still included
in the results.
Using an IN clause with a subquery allows us to remove those rows,
though it's a bit hacky.
(Really I want to be able to use the JOIN on the right side of a LEFT
JOIN to restrict the rows that appear in the results of the LEFT JOIN,
but that doesn't seem to be possible.)
This is similar to the issue fixed by
a920570f04.

Some non-empty loc groups are also unreachable, so I think this was
quite deceptive - e.g. on some OSRS revisions, we'll probably never hit
100% of the keys even if we exclude empty loc groups.
We can include the empty loc flag in the list of missing keys on the
per-cache pages instead.

While the client doesn't appear to be capable of producing a trailing
block with a non-zero next block pointer (though I may have misread the
code), there are caches out there in the wild with trailing non-zero
next block pointers.
When it is reading a group, the client ignores these.
Therefore, for compatibility with the client and existing caches, this
commit removes the StoreCorruptException thrown in this case.
