[Console] Handle zero row count in appendRow() for Table

When a `Table` is created and rendered with no rows (headers only) and subsequently rows are added using `appendRow()`, the first call to `appendRow()` clears back one line too far., thus removing the last run
This is caused by `calculateRowCount()` not accounting for the fact that the footer separator is also the header separator when no rows are present.
This PR works around the issue by checking to ensure that at least 1 row exists before including the footer separator in the row count.
## Example
Command:
```php
<?php
namespace App\Command;
class TableTestCommand extends Command
{
// ...
protected function execute(InputInterface $input, OutputInterface $output)
{
$output->writeln('My table');
$table = new Table($output->section());
$table->setHeaders(['Column', 'Another column']);
$table->render();
$table->appendRow(['Value', 'Another Value']);
$table->appendRow(['Value', 'Another Value']);
}
}
```
Before fix:
```
+--------+----------------+
| Column | Another column |
+--------+----------------+
| Value | Another Value |
| Value | Another Value |
+--------+----------------+
```
After fix:
```
My table
+--------+----------------+
| Column | Another column |
+--------+----------------+
| Value | Another Value |
| Value | Another Value |
+--------+----------------+
```
