Deleting a user account deletes all of the data associated with that user

While upgrading from sentry 3.8.2 to the latest my user account threw a ValueError similar to this one:

File "django/core/handlers/base.py", line 168, in get_response
receivers = signals.got_request_exception.send(sender=self.__class__, request=request)
File "django/utils/decorators.py", line 99, in _wrapped_view
raise
File "sentry/web/frontend/accounts.py", line 25, in login
if form.is_valid():
File "django/forms/forms.py", line 121, in is_valid
return self.is_bound and not bool(self.errors)
File "django/forms/forms.py", line 112, in _get_errors
self.full_clean()
File "django/forms/forms.py", line 268, in full_clean
self._clean_form()
File "django/forms/forms.py", line 298, in _clean_form
self._errors[NON_FIELD_ERRORS] = self.error_class(e.messages)
File "django/contrib/auth/forms.py", line 85, in clean
self.user_cache = authenticate(username=username, password=password)
File "django/contrib/auth/__init__.py", line 58, in authenticate
continue
File "django/contrib/auth/backends.py", line 21, in authenticate
return None
File "django/contrib/auth/models.py", line 275, in check_password
return check_password(raw_password, self.password) 
File "django/contrib/auth/models.py", line 42, in check_password
algo, salt, hsh = enc_password.split('$')

I decided that my user account was somehow invalid so I ran sentry repair and sentry cleanup and finally sentry createsuperuser to create a new account. Once logged into the system, I deleted my old account and renamed the new account to have the same name.

Somehow in this process I ended up with an empty sentry database and lost all of the event data in there.

I was about to solve this when I considered the implications.

I think we'll need to make this behavior configurable, as sometimes we actually want to remove a project when the project's owner is removed.

Perhaps the safety of removing users and projects separately would be better than the possibility of losing data because of misconfiguration :-)

Can any of you guys confirm if this is still an issue?

On 5.4.5 which i believe is last stable release the issue still exists.

I also think that this shouldn't work that way. I created second account and was trying to make it owner of one of the projects but because of ui glitches i was thinking that i didn't acompplished that so i deleted the account and all of data was lost.
