Ignore maximum size for local files when creating previews

It is up to the plugins to decide what sensible size is required for
creating a preview, this cannot be decided by the user for all
plugins. A maximum size only makes sense for remote files, where
the user implicitely decides how much of the bandwith may be used
for having previews.
