Module with 1 cmdlet is not processed correctly

[dermeister0]

Exception is thrown in Update-Progress function:

Exception: Attempted to divide by zero. --> Attempted to divide by zero.

It happens, because $totalCommands is not defined.

$totalCommands = $commandsHelp.Count

Simple fix:

$totalCommands = $commandsHelp.Count
if (!$totalCommands)
{
    $totalCommands = 1
}
