For BUG

When I changed the config source value to ../source,the source images can't be generated.Here is the config:

source_dir: ../source

You can run:

hexo new test
cd ../source
mkdir images
# copy a example image to images
hexo generate

The images folder can not be generated.

@xiaomingplus
One question. Is it only assets (image) only ?
There is a possibility that this issue relate #3410

[xiaomingplus]

@yoshinorin not only image folder,all assets can't be copied to the public dir.
