Remove fix extensions button from extensions dashboard

This partially reverts commit d7d6f54c
by removing the UI from the extensions dashboard but leaving
fix_extensions method in instructor.views.tools. This is ultimately a
hack to fix a deeper platform issue so no need to give it an official UI
within the extensions dashboard. Removing in favor of an XSift that runs
the reapply_extensions management command.
