Can't switch back from replace mode (R) to normal mode using mapped keys

[matrixersp]

Describe the bug
If I use R to replace more than one character, I can't switch back to normal mode with the remapped keys jk ( I use jk to switch to back to normal mode instead of <esc>).

To Reproduce
Steps to reproduce the behavior:

1. Press Shift + r
2. Type a sequence of characters
3. Press j then k

Expected behavior
I expect if I can switch from Replace mode to Normal mode using jk.

Environment (please complete the following information):

• Issue Type: Bug
• Extension Name: vim
• Extension Version: 1.11.0
• OS Version: Linux x64 4.15.0-62-generic
• VSCode version: 1.38.1

Additional context
I think it would be nice if we could do mapping for Replace mode, something like this:

"vim.replaceModeKeyBindingsNonRecursive": [
    {
      "before": ["j", "k"],
      "after": ["<esc>"]
    }
  ]

I would love this.

PR #4735 fixes this. It uses the insertModeKeyBindings and insertModeKeyBindingsNonRecursive which are analogous to Vims imap and inoremap. Insert mode mappings are used both on insert mode and replace mode. I don't think there is a need for specific mappings just for replace mode.

The problem in this issue will be fixed once that PR gets merged.
