Follow-up from "Resolve "Optionally / conditionally mutable parameters""

The following discussion from !228 (merged) should be addressed:

  Another weird thing that is happening is that UUIDs are not working correctly. If a clean session is started from the CL, it is not getting a UUID. For example:

  ~>  texts session -w -r
  Input > %uuid
  Model not found: uuid []
  Input > %bye
  Exiting

  This also happens when using a file:

  ~> echo "a = 4" > tst4.vm
  ~> texts session -w -r -f tst4.vm
  Input > %hist
  COMPLETED  2024-07-26T19:15:59+02:00 a = 4
  Input > %uuid
  Model not found: uuid []
  Input > %bye
  Exiting

  And also if a clean session is started and any variable added. Still no UUID.

  What is a bit more disturbing is the following:

  ~> texts script -w -m workflow -f tst4.vm | tee tst4.log
  program UUID: 805d25df13a341ce9cafb0a6636f939c
  program output: >>>
  
  <<<
  ~>
  ~> texts session -w -r -u 805d25df13a341ce9cafb0a6636f939c
  Input > %hist
  COMPLETED  2024-07-26T19:17:09+02:00 a = 4
  Input >
  Input > %uuid
  Model not found: uuid []

  I tested both my local containerized MongoDB, and our test database.

  Can you reproduce this behaviour?
