fix(format): onTypeFormatting position

[fannheyward]

neoclide/coc-yaml#51

I think the position used in onTypeFormatting is incorrect, in this fix, coc.nvim always uses the current position to request.

I've tested with rust-analyzer/yaml, works as expected. But this fix introduced an unexpected behavior for TS with tsserver:

if (obj) {
  console.log(obj);
}

Put cursor on if, fire cw, the if will be removed and enter insert mode, tsserver returns onTypeFormatting, after applied the edits, you got:

(obj) {
  console.log(obj);
}

the space after if is deleted too.

The reason:

1. coc will check InsertEnter and TextChangedI, try to do onTypeFormatting for o action
2. cw also fires these two event, and tsserver reposed to do formatting
