Description

Following on from comments in #686, this PR:

• Moves the logging of update calls from ve_run into BaseModel.update so it can emit logging that discriminates between the different update modes: normal, initial update of static mode and no update because of static mode.

Fixes #871(issue)

Type of change

• New feature (non-breaking change which adds functionality)
• Optimization (back-end change that speeds up the code)
• Bug fix (non-breaking change which fixes an issue)

Key checklist

• Make sure you've run the pre-commit checks: $ pre-commit run -a
• All tests pass: $ poetry run pytest

Further checks

• Code is commented, particularly in hard-to-understand areas
• Tests added that prove fix is effective or that feature works
• Relevant documentation reviewed and updated
