Series import: downloaded file isn't get removed when exception happens

[php-coder]

When import has failed (because of a seller wasn't specified: #1218), the downloaded file doesn't get removed:

r.m.web.feature.image.ImageServiceImpl   : Image info has been saved to database (ImageInfoDto(id=326, type=JPEG))
w.f.i.FilesystemImagePersistenceStrategy : Image data has been written into file /data/uploads/326.jpeg
r.m.web.feature.image.ImageServiceImpl   : Series #257: image #326 was added

It's not so easy as in order to remove an image we need to have its id and type and we don't have this information within SeriesImportServiceImpl.addSeries() method.

[php-coder]

One way is to modify SeriesServiceImpl.add() to not create an image and execute SeriesServiceImpl.addImageToSeries() manually in the end of SeriesImportServiceImpl.addSeries()
