Editable package can't override the existing non-edtiable version in the working set

[frostming]

• I have searched the issue tracker and believe that this is not a duplicate.

Make sure you run commands with -v flag before pasting the output.

Steps to reproduce

$ pdm add git+https://github.com/pallets/click.git@master#egg=click
$ pdm add -e git+https://github.com/pallets/click.git@master#egg=click

Actual behavior

All packages are synced to date, nothing to do.

The lockfile entry:

[[package]]
name = "click"
sections = ["default"]
version = "8.0.0a2"
editable = true
git = "https://github.com/pallets/click.git"
ref = "master"
summary = "Composable command line interface toolkit"
dependencies = [
    "colorama; platform_system == \"Windows\"",
]

Expected behavior

Editable version is installed in the working set
