issues/184-fixing-undo-step - Adding support for require-pragma

- Our previous undo implementation tried to be naive on implementing
require-pragma, and created some undo bugs due to it. This diff enables
us to use the prettier upstream support for require-pragma
- On subsequent PR's we will completetly phase out the previous undo
implementation in favour to this one in order to fix bug https://github.com/prettier/vim-prettier/issues/184
