Add a test showing our behavior when migrating from an optional column to a required column.
...
Optional values are not automatically migrated to required columns since it is a lossy process.
This test case revealed an issue where the number of objects can be lost if all properties of an
object were optional and are all being migrated to required. This happens because the migration
process removes the optional columns in a first pass, and recreates them as required in a second
pass. Since this results in all columns being removed, we lose track of how many objects were
stored. We avoid this by detecting the case where we are about to remove the last column and
inserting a placeholder column that we'll remove after inserting the new columns.

Support migrating required columns to optional, preserving their contents.
...
Required columns are migrated to optional by creating a new nullable column,
copying the data from the required column to the optional column, then removing
the original required column.

Refactor schema initialization a bit
...
Change schema verification to operate on a pair of Schema objects rather than a
Schema and a Group to eliminate some redundant work done, defer some of the
work done for migrations to within the migration block to avoid doing it
unnecessarily, and make passing in a custom schema in the Config when creating
a Realm entirely equivalent to calling update_schema() afterwards.
