Throw when a block action element is a select and 'Clear Selection' is clicked.

[reesesm2000]

When sending an actions block as an interactive message with an external_select element there is a 'Clear Selection' option in the dropdown list. If you select 'Clear Select', there is a throw in slack_adapter.js at line 546 as there is no selected_option. Following line needs to be adapted to cater for null values.

From:

                        activity.text = event.actions[0].selected_option.value;

To:

                        activity.text = event.actions[0].selected_option ? event.actions[0].selected_option.value : undefined;
