There are a few collisions in the production archive. I suspect these
are due to poorly modified caches, and tracking the source(s) of each
group will make it easier to determine which cache is probably
problematic.
This change also has the benefit of removing a lot of the hacky source
name/description merging logic.

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.
