fix: --name option for the create-tenant command does not take effect

[euxx]

Summary

Fixes #11991

The issue is:

When run create_tenant command, it first registers an account, and then call create_owner_tenant_if_not_exist method. （api/commands.py:565）

However, a default tenant will be created during the register account process.

    # api/services/account_service.py:815
    def register(
        ...
    ) -> Account:
        create account...

            if FeatureService.get_system_features().is_allow_create_workspace:
                tenant = TenantService.create_tenant(f"{account.name}'s Workspace")

Therefore, a tenant will always exist when create_owner_tenant_if_not_exist is called, and won't create a tenant with --name option.

    # api/services/account_service.py:517
    # available_ta will always be true
    def create_owner_tenant_if_not_exist(
        account: Account, name: Optional[str] = None, is_setup: Optional[bool] = False
    ):
        """Check if user have a workspace or not"""
        available_ta = (
            TenantAccountJoin.query.filter_by(account_id=account.id).order_by(TenantAccountJoin.id.asc()).first()
        )

        if available_ta:
            return
