Exception on node delete.

Problem/Motivation

I am getting this exception when deleting nodes.

The website encountered an unexpected error. Please try again later.</br></br><em class="placeholder">Drupal\Core\Entity\EntityStorageException</em>: External URLs do not have internal route parameters. in <em class="placeholder">Drupal\Core\Entity\Sql\SqlContentEntityStorage-&gt;delete()</em> (line <em class="placeholder">731</em> of <em class="placeholder">core/lib/Drupal/Core/Entity/Sql/SqlContentEntityStorage.php</em>).

I've traced it to CacheTagsInvalidator::getTagsBySourcePath().
Method is called with the same node 2 times and on the second one it is getting the exception.

The aliases on the node are all for different languages.
The ones that are failing are deleted languages (stale aliases).

Proposed resolution

Catch the exception and return empty result in that case...
