Plugin linemarkers is missing for interface methods

[andrewbess]

Describe the bug (*)

The system doesn't navigate from plugin to the subject method if a plugin has been created to an interface. There no special linemarker to navigate. However, if you create a plugin for the class the linemarker will be added and the system navigates successfully.
Take a look at the screenshots below.

To Reproduce (*)

Steps to reproduce the behavior:

1. Create a plugin to interface
2. Go to created plugin method
3. Pay attention to the gutter icons panel

Expected behavior (*)

The gutter icons panel has a linemarker with the hint "Navigate to target method" and the system has a possibility to navigate there.
