[ *generate:module* ] Error: Call to a member function getPath() on null when module name starts with a number

[Xarno]

Problem/Motivation

When generating a module with a number as first char the drupal console throws an error.
I had no idea why and tried around for half an hour. That case should handled properly.

How to reproduce

drupal generate:module --module="3rdparty_roles" --machine-name="3rdparty_roles" --module-path="modules/custom" --description="Allow granting roles to users at signup time. For that a list of allowed users is maintained." --core="8.x" --package="Custom" --module-file

Result:

// generate:composer

Details to include:

• Drupal version: 8.6.17
• Console version: 1.9.3
• Console Launcher version: 1.9.3

Solution

Don't use a number as first char?! If this is forbidden then don't crash. Print a nice error message instead.
