incorrect root link through the flag

[kalwalt]

Hi;
When you click on the flag and visit http://127.0.0.1:8000/it/ than click on the English flag to return to the English version it end with a double slash
http://127.0.0.1:8000/en//
note the same thing happen when you are at http://127.0.0.1:8000/en/ and click on the Italian flag.

Yes @JOduMonT i saw this, but hadn't the time to fix.
I think i need to add another check in this function

gatsby-starter-i18n-bulma/src/components/Layout.js

Lines 51 to 58 in 5107c97

	const setLangsMenu = ( langsMenu, id, basePath, jsonData) => {
	if(id !== 'undefined'){
	langsMenu[0].link = `/en/${basePath}` + getIdJsonUrl(id, 'en', jsonData) + '/';
	langsMenu[1].link = `/it/${basePath}` + getIdJsonUrl(id, 'it', jsonData) + '/';
	}else{
	console.log("missed id in the setLangsMenu() function!");
	}
	};

to not add the extra / if the link is the root /it/ or /en/.

I suppose something like this (not tested at all):

const setLangsMenu = ( langsMenu, id, basePath, jsonData) => { 
   if(id !== 'undefined'){
    if (id=='01') {
      langsMenu[0].link = `/en/`;  
      langsMenu[1].link = `/it/`; 
     } else {
        langsMenu[0].link = `/en/${basePath}` + getIdJsonUrl(id, 'en', jsonData) + '/';  
        langsMenu[1].link = `/it/${basePath}` + getIdJsonUrl(id, 'it', jsonData) + '/'; 
     }
  }else{  console.log("missed id in the setLangsMenu() function!");  }
};

@JOduMonT i'm working on this branch https://github.com/kalwalt/gatsby-starter-i18n-bulma/tree/fix-lang-switch if you want to test, it seems that be3a25b fix the issue.

Should be solved with #145, closing for now.

I have tested in different situations and don't completely solve the issue: the solution in the last commit works for the home page but not if you change the page from a page like /artworks to /home it will add an extra /. This happens clicking on the logo. I will open a new issue for this.
