No difference between single and double quoted strings

@vpetrovykh đang làm issue này rồi.

Từ ngày 4/2/2019.

Ok I'm sorry if I don't take the time to use your template and try to prepare a pull request and all that stuff. I'm just not used to it.

I already spent much time on solving the issue for myself. And I only post here to share my solution.

If somebody is experimented with pull requests and all those things, below is my diff.

Also, if anybody finds this issue from google they will have the option to just apply the diff.

**SOLUTION**

Put the fix-string-quoted-double.patch (file below) in the relevant location of the extension.
Should be something like `~/.vscode/extensions/magicstack.magicpython-1.1.0/grammars/src`

Then go to this location and execute `git apply fix-string-quoted-double.patch`

> fix-string-quoted-double.patch
