Imagefield_import doesn't work if settings form has not been submitted once

Hello,

This seems fishy to me that, even if imagefield_import's settings form is displaying the right path out of the box, it won't import images.
This is because different values are given to variable_get('imagefield_import_path', ...). I suggest always using the same default value (the one used to pre-fill the settings form). Patch is attached.

Regards,

David
