Ctrl-E shortcut not working with FakeVim mode when cppeditor plugin is turned on.

Reproduce flow:

• start Qt Creator without loading any project
• File -> Open File or Project ...
• select any file with .cpp (or .h) ending
• move the viewport to the middle of the file
• press Ctrl-E -> nothing happens.
• open a file of another file type, e.g. a SQL-file
• Ctrl-E work as expected

I believe the bug is introduced by the following change:
