What happened: While implementing #2517, we realized that VimError (error.ts) exceptions are not displayed on the status bar.

What did you expect to happen: VimError message to show up on the status bar.

How to reproduce it (as minimally and precisely as possible): Just after launching VSCode with VSCodeVim pluging installed, try a substitute with no search pattern: e.g. %s//test/. An error E35: No previous regular expression should appear on the status bar.

Environment:

• Extension Name: vim
• Extension Version: 0.11.3
• OS Version: Darwin x64 17.4.0
• VSCode version: 1.22.1
