"New Project" silently deletes project directory

[konradkonrad]

How to reproduce

When I point the "New Project" directory to an existing directory like this:

$ pwd
/home/user/code
$ ls -R
.:
testproject

./testproject:
firstcontract.sol  secondcontract.sol

Now I create a new project named testproject inside /home/user/code.

Actual Outcome

The result is, that all files inside testproject are replaced with mix' standard scaffolding files:

$ ls -R
.:
testproject

./testproject:
contract.sol  index.html  package

./testproject/package:
compilation

./testproject/package/compilation:
contract.sol.js

I.e. my existing files firstcontract.sol and secondcontract.sol got deleted!

Expected Outcome

IMO this is unexpected behavior for an IDE. It should never delete files without explicit user action (e.g. 'FILE.contextmenu -> DELETE'). In the case of creating a new project over an existing folder it should either:

• come up with a warning (minimal) or
• merge the standard scaffolding with the existing directory and have confirmations for all conflicting/existing files (better)

This looks to be the same issue as ethereum/webthree-umbrella#521, eh?

@chriseth @yann300 @LianaHus This is a pretty catastrophically terrible bug.
