Using poetry from master/develop branches or any recent alpha/beta release,
you can't add the requests package with the security extra.
The requests package requires the idna twice
(as a main dependency and as an optional one) and this case wasn't handled
properly in Locker._dump_package function.
These changes make the _dump_package ensures that
all elements of the constraints list have the same type
in order to make them renderable as TOML.

Resolves: #1401

* Use os.execvp for poetry run

* Use subprocess.Popen for Windows

* Handle env kwargs

* Fix specification of Python versions for dependencies using double
  pipe (`||`) instead of using an array which leads to confusion (see for
  instance https://github.com/sdispater/poetry/issues/847).

* Fixes #847

Some packages (like `pygame-music-grid`) have unparseable metadata.
This resulted in a ValueError. pip ignores packages like these, so it's reasonable
to do the same in poetry itself and only display the well-formed ones.

Fixes #1345.
Fixes #637.
