Bug in linking resources folders of components when they have a different interface name

[furkan3ayraktar]

Describe the bug
PR #21 causes tests failing after merging fixes to tests in PR #18. The reason of this is delete command does not delete the right resources folder, which is named with the interface name. Also same PR introduced another bug where if you create a new component with a different interface, it links the wrong resources folder to the system. This results in a bad behavior in remove command as well.

To Reproduce
Steps to reproduce the behavior:

1. create s system-1 base-1
2. create c component-1 interface-1
3. add component-1 system-1
4. Check resources folder under system-1. You'll see a wrong symbolic link with component name.
5. delete c component-1
6. Check resources folder under development environment. You'll see a broken symbolic link to interface-1

Expected behavior
System should have correct resources folder linked.
Development environment shouldn't have symbolic link.
