Fix fs copyFile when source and target are the same

rosen-vladimirov · rosen-vladimirov · commit 638ad5bf1f6f · 2015-10-27T12:32:49.000+02:00
When source and target file are the same, copyFile produces empty file.
Add check and if they are the same, do not execute any action.

Move fs tests from appbuilder-cli to common. Add tests for copyFile.
