Issue
When using a path-based dependency, trying to add a new package that conflicts with a sub-dependency leads to an infinite loop.

from distutils.core import setup
setup(

version="1",
py_modules=["foo"],

install_requires=["requests~=2.25.1"],
)At first, I run poetry install --sync --no-root
$ poetry install --sync --no-root

• Installing requests (2.25.1)
• Installing foo (1 /Users/julius/src/debug_poetry/my-package)
Then, if I try to add requests@latest, poetry goes into an infinite loop:
$ poetry add -vvv requests@latest | less
