Fix copying of static files

This patch fixes file copying for addComponent().

[bajtos]

I am confused, the patch seems to contain two changes:

1. fix construction of tasks, so that template files are copied
2. add exec function that is used only in tests so far

What do you intend to use exec for?

[bajtos]

Seems the exec function is not that useful at the end. What modules are missing? Perhaps they can be added to workspace dev-dependencies?

[bajtos]

I am proposing the following steps:

• Remove exec. Modify unit-tests to check for the presence of files only.
• In a new pull request, write end-to-end test that will
  1. Create a new app from template
  2. Create node_modules folder in the project dir
  3. Run npm install in the project dir
  4. Start the scaffolded app, run the following scenario using supertest: create user, login, get user details.

That should catch most of the problems in templates. I have already fixed few of them in #63.

Remove exec. Modify unit-tests to check for the presence of files only.

Done. Can we merge this now?

[bajtos]

This test does not assert anything, it should be removed IMO.

[bajtos]

Removed in #63.

I have merged this pull request as it was blocking my progress. The comment above can be addressed in a new pull request.
