poetry remove --dry-run modifies poetry.lock

[samestep]

• 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: macOS Big Sur Version 11.2
• Python version: Python 3.8.3
• Poetry version: Poetry version 1.1.4
• Link of a Gist with the contents of your pyproject.toml file: https://gist.github.com/samestep/7fab4df48b7b4f89ea5fe5c29f7d4692

Issue

As the title states, running poetry remove --dry-run modifies poetry.lock. Example:

poetry new remove-dry-run-bug
cd $_
sed -i '' 's/^authors = \[".*"\]/authors = []/' pyproject.toml
cat pyproject.toml # see gist
poetry add pyyaml
cp poetry.lock{,.old}
poetry remove --dry-run pyyaml
git diff --no-index poetry.lock{.old,} | tee poetry.lock.diff # see gist

This causes subsequent commands (such as poetry show) to fail.

Yeah I'm on the latest version of poetry and just ran:

poetry add djangorestframework@latest --dry-run just to test what it would do and it updated poetry.lock (it did not update the actual package locally).

This seems pretty bad no?
