Type prefixed functions display wrong signature upon hover

[gnikit]

This should display the function signature instead of a, what I can only assume without testing, is a var signature

integer function foo(x, y) result(z)      ! result does not need to be present for this to occur
  integer, intent(in) :: x, y
end function foo

[gnikit]

This is due to returning the object associated with the implicit result variable and not the function itself, i.e. should return FSQN of foo instead returns foo::foo which is implicitly defined as a member variable during the parsing of foo. AFAIK this is only applicable to functions, so rewriting the entire scope retrieval for just one of the scope cases is too much. For now, I will add it a special case to the scope retrieval process.

Fixing this should also fix locating references and going to definitions, since all of these actions rely on get_definition
