pam does not respect previously existing root language folder

[yurj]

Hi!

I've a site with / set as italian (TG is ok) and /en as english. It works (had to set it by code because related widget does not support picking the root) but when I save the language control panel, setup.py will set /it as italian translation for /en. This is due to this lines:

plone.app.multilingual/src/plone/app/multilingual/browser/setup.py

Lines 71 to 75 in 80c0af2

	available = language_tool.getAvailableLanguages()
	for language in languages:
	info = available[language]
	name = info.get("native", info.get("name"))
	doneSomething += self.setUpLanguage(language, name)

this lines does not check if there's an already existing translation.

Will you accept a patch that just check if an already existing root language folder exists and then skip the setUpLanguage call?

The real fix shoudl be to change this:

plone.app.multilingual/src/plone/app/multilingual/browser/setup.py

Line 136 in 80c0af2

folder = getattr(self.context, folderId, None)

to get the existing root translation folder.
