Fix accessibility problem of "interactive controls must not be nested" on FileUploader and JobLogs components.

Axe tools shows (2) "interactive controls must not be nested" on Data Import module Landing page, home screen related to STDTC. The first problems comes as a result of FileUploader component having nested Focusable elements with the role of button. And the second one comes from the result of adding select all checkbox button at the headColumn and not being able to pass nonInteractiveHeaders prop to MultiColumnList via JobLogs, and thus having nested controls.
