Allow navigation to folders from search results (#1209)

* Allow navigation to folders from search results

- Uses router to pass ID of the folder
- Modified document list component to accept folder ID without path
- Current limitations
  - Breadcrumb cannot currently be shown when navigating via folder id
  - Clicking between folders does not update the current route

* Allow root folder ID to be changed and have documentlist reload

- e.g switching from Company home to My Files

* New tests for navigating to folders based on ID
