[Bugfix] fixes and code cleanup to update and installation routines (#3101)

- Fix the update script to work again and fixes the ambiguity between
when a user wants to update to a tag vs updating to a branch, by making
these two operations explicitly separate.
- Remove dangling functions and arguments related to legacy checkpoint
conversion. These are no longer needed now that all legacy models are
either converted at import time, or on-the-fly in RAM.
