only_blobs and created directories

[kuba]

If you set:

[backup]
recipe = collective.recipe.backup
blob_storage = ${buildout:directory}/var/blobstorage
only_blobs = true

Then all the directories, including ones defined by backup_location and snapshot_location, are created. Those 2 are redundant and will always stay empty and therefore check_folders should not create those folders if only_blobs is set to true.

Good point. I have released 2.16 with a fix.
