Spurious version conflict

[dmyersturnbull]

• [x] I am on the latest Poetry version.
• [x] I have searched the issues of this repo and believe that this is not a duplicate.
• [x] If an exception occurs when executing a command, I executed it again in debug mode (-vvv option).

• OS version and name: Windows 10
• Poetry version: 1.0.10
• Link of a Gist with the contents of your pyproject.toml file: https://gist.github.com/dmyersturnbull/066ed76847816495a1638157e44445f9

Issue

This appears to be a spurious conflict:
Because pocketutils depends on both peewee (>=3.13, <1.0) and peewee (>=3.13, <1.0), version solving failed.

Hello @dmyersturnbull,

there are some mistakes in your pyproject.toml here:

PyMySQL                  = {version=">=0.10, <1.0", optional=true}
peewee                   = {version=">=3.13, <1.0", optional=true}
sshtunnel                = {version="0.13, <1.0", optional=true}

You are saying the peewee version must be greater >=3.13 and smaller <1.0. Both criteria cannot be valid at the same time.

Furthermore the sshtunnel version must be exact 0.13 and smaller 1.0. While this can be valid, the current version of sshtunnel is 0.1.5. So poetry will fail here as well.

Also you have specified tomlkit twice as a dependency.

Oh wow, I have no idea how I didn't notice that. Thanks.
