exporting to requirements.txt always prepends -e to dependencies

• [x] I am on the latest Poetry version.

• [x] If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• Poetry version: 1.0.0b8

Issue

As reported by @petergaultney in https://github.com/sdispater/poetry/pull/1630 -e get always prepended for folder dependencies regardless develop = false is set in pyproject.toml or not.

Further investigation has shown, that this setting isn't transported poetry.lock. Overall develop = false doesn't have any effect as expected for now.

This also fails for urls:

en-core-web-sm = {url = "https://github.com/explosion/spacy-models/releases/download/en_core_web_sm-2.2.0/en_core_web_sm-2.2.0.tar.gz"}

becomes

-e https://github.com/explosion/spacy-models/releases/download/en_core_web_sm-2.2.0/en_core_web_sm-2.2.0.tar.gz

instead of

https://github.com/explosion/spacy-models/releases/download/en_core_web_sm-2.2.0/en_core_web_sm-2.2.0.tar.gz \

Hello @NoahTheDuke ,

thanks a lot for reporting this!

The correct use of -e for folder dependencies is now fixed by python-poetry/poetry#1656 .

The fix for url dependencies need some more work. I already found out, what have to be done and I will provide another PR the next days.
