material-table: When options={selection: true} is set the actions column does not appear for the table

Describe the bug When options={selection: true} is set the actions column does not appear for the table.

To Reproduce Steps to reproduce the behavior:

1. Create a standard MaterialTable component
2. Add props options={{selection: true}} and actions={[{ icon: 'account_circle', tooltip: 'test', onClick: (event, rowData) => { console.log(rowData);}}]}
3. View table in browser
4. Notice the checkbox column overwrites the Actions column. This also occurs if you try to change the actions column index.

Expected behavior Actions column should be added after the checkbox column on index 1 (assuming 0 indexed table columns) and to the left of the table data.
