DennisOSRM/Project-OSRM — Issue #140: unnamed ways causes instructions for each node passed

State: open

when routing on a way without a name tag, or an empty name, osrm returns an instruction for every node passed, even though it's the same way.

a failing test is in my way_name_testing branch, see #139

```
Scenario: Don't create instructions for every node of unnamed ways # features/names.feature:31
Given the nodes # features/step_definitions/data.rb:15
| a | b | c | d |
And the ways # features/step_definitions/data.rb:32
| nodes | highway | name |
| abcd | cycleway | |
When I route I should get # features/step_definitions/routing.rb:190
| from | to | route |
| a | d | cycleway | <-- expected
| a | d | "","","" | <-- got
Tables were not identical (Cucumber::Ast::Table::Different)
