Conjunction produces wrong dollar parameter placeholders

[strider2038]

Alongside with #286 using Or or And affects wrong placeholders.

This test reproduces the problem.

func TestSelectSubqueryInConjunctionPlaceholderNumbering(t *testing.T) {
	subquery := Select("a").Where(Eq{"b": 1}).Prefix("EXISTS(").Suffix(")").PlaceholderFormat(Dollar)

	sql, args, err := Select("*").
		Where(Or{subquery}).
		Where("c = ?", 2).
		PlaceholderFormat(Dollar).
		ToSql()
	assert.NoError(t, err)

	expectedSql := "SELECT * WHERE (EXISTS( SELECT a WHERE b = $1 )) AND c = $2"
	assert.Equal(t, expectedSql, sql)
	assert.Equal(t, []interface{}{1, 2}, args)
}
