ext.viewcode following imports does not put correct [docs] links.

[Viech]

My top level package imports some objects from subpackages and submodules so that users can access them directly. viewcode_follow_imported_members is made to still find the correct source file in this case. However, the [docs] link that should lead back to the documentation leads to the documentation of the submodule that actually contains the code (which is perfectly fine), but the jump label references the object's alias in the top level package, which is not defined like that on the submodule's documentation page.

To be more clear:

The top level package package has a package.html file that documents package.MyClass. Now MyClass is really defined in the source module package/submodule.py. The [source] link in package.html takes me to _modules/package/submodule.html and the correct code line. But the [docs] link there takes me to package.submodule.html#package.MyClass. The #package.MyClass part is incorrect; such jump label doesn't exist there. The correct jump label would be #package.submodule.MyClass.
