Description

There are several places that use JobId.toShortString() instead of the full JobID, for unique directories, etc.

I think we should drop that method.

• If the short String representation (8 bytes) is statistically "unique enough", then it is wrong in the first place that the unique IDs have 16 bytes
• If 16 bytes were chosen with a purpose, then using the short string representation in paths, etc, is clearly violating the guarantees the IDs try to give,

For purely informational logging, it may be a nice util, bit it seems to encourage wrong use.
