fixture: watch cannot build when files are changed or added successfully

[ghost]

1. For function 'fullBuild', the first statement 'opts' can be divided into two parameters called "selectedLocales" and "reserveLocale", the order isn't right, according to the caller of this function itself (See its calling at server.js by 'build.fullBuild' and other related functions). So switch them together.

2. Fix watch is broken #2443 (comment) for watch, because we didn't pass the parameter into the buildLocale, there'll be Unhandled Exception.

@MaledongGit Please see #2443 (comment)

Something is wrong anyway in serve.js. IMO we should adjust serve.js.

Watch is broken not build. Just try editing a markdown file from any locale.

@XhmikosR , OK, In fact I've fixed it locally, but since you've mentioned me by this, I'll submit mine here;)

@MaledongGit: your patch works when there's one locale set in DEFAULT_LOCALE. When there's more than one, it doesn't work properly.

I'd say, drop this patch from here and let's tackle it in a separate branch. We probably need to export generateLocalesData in build.js and use this in server.js.

When I don't set a default locale, and I change for example an English md file, after rebuild, I get this in the browser console:

TypeError: currentLangElement is null
en:116:22

It might not be related to this patch, though.

That being said, with your patch, if I have DEFAULT_LOCALE=en and I change a German content file for example, I see the console message that it changed but it's useless since we aren't watching for files other than DEFAULT_LOCALE. Maybe remove your console messages completely.

@XhmikosR， No problem, I'll repost it and give you the feedback of my result, still say "A BIG THANKYOU!"
