* First draft:in js, constructor declaration is preferred
* Add tests
* initializer of null|undefined gives any in JS
Also move this-assignment fixes out of binder. I'm going to put it in
the checker instead.

@amcasey: Preserve leading trivia when organizing imports
When organizing imports, we used to move the leading and trailing trivia
of each individual import with that import as it was repositioned or
deleted. This had the unfortunate effect of repositioning or deleting
the header comment of the file.
Our new approach is to leave the leading trivia of the first import
ahead of the resulting block of imports (i.e. it no longer follows the
first import as it is repositioned or deleted). Trailing trivia on the
first import and trivia on subsequent imports are treated as before.
There are times when the directory watcher for failed lookup locations isnt invoked and is not very determinitstic
So as a fallback, when we receive typeRoots watch event, handle failed lookup locations as well
