[PALEMOON] Fix: The profile resseting - partially

https://github.com/MoonchildProductions/UXP/commit/aaf3409c46a5e472bc539a6ad5902f886c980e1f

- Revert migration
- Partially
- no manual migration from Places
- no migration from other browsers
- no the cmd `-migration`
- Fix migration files (`// Tycho:`)
- Something in the last commit (a typo)
