    Fix incomplete pop-up message on delete Action

    When an Action table is created with a 'danger' action_type and a
    single handler method for a single object, the 'selection' and
    'help' parameters are empty. This causes the pop-up message to be
    incomplete. For example:

    "You have selected: . Please confirm your selection. "

    This patch fixes this behaviour by displaying the message with
    the selected objects only when one or more objects are selected.
    Otherwise, it only asks for confirmation.

    Test Plan:
    PASS: Build python3-django-horizon package including these changes.
    PASS: Test the behaviour for single delete actions. For example:
    Create a patch strategy and press the "Delete" action. Verify
    the following message is displayed in the pop-up message:
    "Please confirm your selection. This action cannot be undone."

    PASS: Test the behaviour for multiple delete actions. For example:
    Upload more than one patch, select them and click on the 'Delete'
    action. Verify the following message is displayed:
    You have selected: "22.12_NRR_INSVC", "22.12_RESTART_FAILURE_INSVC".
    Please confirm your selection. This action cannot be undone.
