Issue

When given the above pyproject.toml file, running poetry lock on Linux generates the following poetry.lock:

[[package]]                                      
name = "test"                                  
version = "1.0"                                  
description = ""                                 
category = "main"                                
optional = false                                 
python-versions = "*"                            
                                                 
[package.source]                                 
type = "file"                                    
url = "wheels/test-1.0-cp34-abi3-win_amd64.whl"

Also, poetry export outputs:

test @ file:///home/nyuszika7h/example/wheels/test-1.0-cp34-abi3-win_amd64.whl; sys_platform == "win32" or sys_platform == "linux" or sys_platform == "darwin"                               

The expected behavior would be to include 3 separate entries, one for each platform.

Interestingly enough, poetry install is smart enough to pick the correct version for the platform despite the incorrect locking. But the lock file is incomplete, and the requirements.txt output is just completely wrong.
