Add read replica testing helpers and fix non-sso login bug (#4908)
not set on the INSERT.
- OUT: Only sets the ID on the passed session and returns it. (`CreatedAt`, `AccessedAt`, are not set.)

New version:

```go
func (ds *Datastore) NewSession(ctx context.Context, userID uint, sessionKey string) (*fleet.Session, error) {
	sqlStatement := `
		INSERT INTO sessions (
			user_id,
			` + "`key`" + `
		)
		VALUES(?,?)
	`
	result, err := ds.writer.ExecContext(ctx, sqlStatement, userID, sessionKey)
	if err != nil {
		return nil, ctxerr.Wrap(ctx, err, "inserting session")
	}

	id, _ := result.LastInsertId() // cannot fail with the mysql driver
	return ds.sessionByID(ctx, ds.writer, uint(id))
}
```

- IN: Define arguments that are truly used when creating a session.
- OUT: Load and return the fleet.Session struct with all values set (using the `ds.writer` to support read replicas correctly).

PS: The new `NewSession` version mimics what we already do with other entities, like policies (`Datastore.NewGlobalPolicy`).
