Title: fixbug for get part of filename when filename contains two '.'

when use [Building the files object dynamically](http://gruntjs.com/configuring-tasks#building-the-files-object-dynamically)
like this:
```js
{
expand: true,
src: [PATH_SRC + APP_NAME + '/*.js', PATH_SRC + APP_NAME + '/**/*.js'],
dest: PATH_DEST,
ext: '.js',
rename: function(dest, src) { console.log(src);
var version = getVersion(src, PATH_TMP + APP_NAME + '.json', grunt);
return version && (dest + version);
}
}
```
If there has a js file like zepto.min.js, and the output is zepto.js.
