the class PrimaryKeyTests method removingPrimaryKeyRemovesConstraint_typeSetters.

/**
 * This test surfaces a bunch of problems, most of them seem to be around caching of the schema
 * during a transaction
 *
 * 1) Removing the primary key do not invalidate the cache in RealmSchema and those cached
 *    are ImmutableRealmObjectSchema so do not change when the primary key is removed.
 *
 * 2) Addding `schema.refresh()` to RealmObjectSchema.removePrimaryKey()` causes
 *    RealmPrimaryKeyConstraintException anyway. Unclear why.
