Fix. Clear the "paths" instance variable before loading Magic database
Fix. Clear the "paths" instance variable before loading Magic database

Add the code that has been removed in the following commit:

  - eed9a75 ("prefactor: always use @paths to store paths"

We want to set the "paths" instance variable to an empty value should
loading from a provided path failed, as this should indicate that no
healthy Magic database is currently available.
