Currently, the scripts are loaded based on the lexicographical order of
the absolute paths of the scripts. This makes it difficult to control
the load order. This change bases the load order solely on the filename,
as was originally used before
https://github.com/eclipse/smarthome/pull/3855, and preserves the
ability to use scripts with the same filename.
