"""
Test the error when no will-executor is selected and ``no_willexecutor``
is ``False`` (the "Add transactions without willexecutor" checkbox is
unchecked), using the real **karen7** regtest wallet.
Scenarios covered by this test
------------------------------
A. ``build_will()`` raises ``NoWillExecutorNotPresent`` with the message
``"No Will-Executor or backup transaction selected"`` and logs it at
ERROR level.
B. ``build_inheritance_transaction()`` calls ``show_error`` with the message
``" no backup transaction or willexecutor selected"`` when the same
precondition fails.
C. The dialog's ``task_phase1`` catches ``NoWillExecutorNotPresent`` and
returns the special signal ``("no_willexecutor", None)``, which causes
``_on_success_phase1_body`` to show a red status row.
D. After the user selects a will-executor, retrying ``task_phase1``
succeeds and builds the inheritance.
