Issue Description:

protocol Aaa { 
    func bbb()
}
class Ccc { 
    func bbb() { } //5
}
extension Ccc: Aaa { } //7
class Ddd: Ccc { } //8

If you ask for implementations for function `bbb` in the protocol, Sourcekit-LSP will return positions at lines 7 and 8. I would expect it to return the position of the method at line 5.
