sqlmock panics when closing empty Rows object

[raxod502-plaid]

Operating system and Go Version

macOS 14.4.1, Go 1.20

Issue

When using db.Query to perform a query that does not return any rows, sqlmock panics instead of performing a no-op as other database drivers do.

A workaround is to use db.Exec instead so that there is no rows object to close, but the sqlmock behavior is incorrect.

Reproduction steps

package main

import (
	"github.com/DATA-DOG/go-sqlmock"
)

func assert(err error) {
	if err != nil {
		panic(err.Error())
	}
}

func main() {
	db, mock, err := sqlmock.New()
	assert(err)
	mock.ExpectQuery("TRUNCATE table").WithoutArgs().WillReturnRows()
	rows, err := db.Query("TRUNCATE table")
	assert(err)
	err = rows.Close()
	assert(err)
}

Expected Result

No error (or, at worst, an error returned from rows.Close)

Actual Result

panic: runtime error: index out of range [0] with length 0
