Fix view IDs

Summary:
A few view IDs in the documentation had been fixed already but missed in
the view implementation files.

This does not fix each and every view but at least the general plugin list
should be fixed now.

Fixes T27563

Test Plan: Press F1 in the views and check that the context-specific documentation is shown.
