When a LDAP user signs in the for the first time and if there
is an `Identity` object with `user_id` of `nil`, new users
will not be able to be register until that entry is cleared
because of the way identities are created:

1. First, the User object is built but not saved, so it has no `id`.
2. Then, `user.identities.build(provider: 'ldapmain')` is called,
   but it does not have an associated `user_id` as a result.
3. `User#save` is called, but the `Identity` validation fails if an
   existing entry with `user_id` of `nil` already exists.

The uniqueness validation for `nil` values doesn't make any sense in
this case. We should be enforcing this at the database level with a
foreign key constraint. To work around the issue we can validate
against the user instead, which does the right thing even when
the user isn't saved yet.

After the import has finished, we flush (delete) the InternalId records
related to the project at hand. This means we're starting over with
tracking correct internal id values, a new record will be created
automatically when the next internal id is generated.

The GitHub importer assigns iid values by using supplied values from
GitHub. We skip tracking internal id values during the import in favor
of higher concurrency. Deleting any InternalId records after the import
has finished is an extra measure to guarantee consistency.
