poetry init fails when pyproject.toml exists and --dependency is specified

[amaralbf]

• I am on the latest Poetry version.

• I have searched the issues of this repo and believe that this is not a duplicate.

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

• OS version and name: Ubuntu 16.04 (Xenial)

• Poetry version: 1.1.0

• Link of a Gist with the contents of your pyproject.toml file: https://gist.github.com/amaralbf/f5a2d2f24b72235f5f8ff53a3182c272

Issue

First of all, thank you so much for putting so much effort into this project! It's been my favorite tool for packaging and managing my projects' dependencies.

The issue I've encountered occurs when I try to execute the poetry init command and:

1. a pyproject.toml already exists (and has no poetry sections);
2. and one or more --dependency or --dev-dependency are specified.

If I run poetry init without specifying any --dependency or --dev-dependency, it works as expected.

Example

pyproject.toml

Command: poetry init -n --dependency numpy -vvv

• (I get exact same Stack trace if I run the command interactively)

Output:

This command will guide you through creating your pyproject.toml config.
