Fix upload_image error in stackrc
This commit fixes error caused by adding default image path to IMAGE_URLS without ','
If user sets IMAGE_URLS in localrc like
IMAGE_URLS="path1, path2" (with a space after the comma)
the we get an error "binary operator expected" in
if [ -n $IMAGE_URLS ] condition and a comma will not be added to the end of IMAGE_URLS
In the code below we add default image path(path3) to IMAGE_URLS and we get
IMAGE_URLS="path1, path2path3"
