[FIX] board: handle actions with no view_mode

The view_mode attribute is automatically set to the 'action' nodes
when the action is added to the dashboard using the 'Add to
dashboard' button in the searchview. However, other dashboard views
can be written by hand (see openacademy tutorial), and in this
case, we don't want to hardcode action's params (like context or
domain), as the dashboard can directly retrieve them from the
action. Same applies for the view_type, as the first view of the
action can be used, by default.

Before this rev., the second usecase wasn't handled, and it crashed
when no view_mode was specified. This rev. also ensure that the
context and domain are correctly retrieved from the action.

Closes #24088

closes odoo/odoo#27517
