[FIX] website: can not change website name

The website name is by default "localhost" (used in the page title in the format
"Current Page | Website Name") but there were no way to change it.
Fixes #3493
[FIX] analytic_user_function: inherit conflict on account type

The field account_id was inherited with position="replace" meaning we erased
future changes made into hr_timesheet_sheet (41f2eba missed "type in []" and
65f31b9 missed use_timesheets).
Replace by position="attributes" to only change what matters: the on_change.
Fixes #3974
