Problem/Motivation

When trying to run drush dmu-upgrade I encountered this fatal error:

Error: Call to a member function append() on null in Drupal\drupalmoduleupgrader\Plugin\DMU\Converter\PSR4::toPSR4() (line 54 of /var/www/html/web/modules/contrib/drupalmoduleupgrader/src/Plugin/DMU/Converter/PSR4.php).
 [warning] Drush command terminated abnormally.
Failed to run drush dmu-upgrade partial_date: exit status 1

Steps to reproduce

Download and attempt to upgrade the partial_date module.

Proposed resolution

Add code to check that the returned namespace is not null before attempting to use the append method. This would be easier in PHP 8 using the null safe operator, but for backwards compatibility use the longer way to achieve this.
