Version update also updates the a public dependency

[miraclx]

This is a tricky one..

Provided a workspace, with the members foo, bar and syn.

• foo depends on the local syn at path ../syn
• bar depends on the public crate syn from crates.io

cargo ws version major will act on all the local crates foo, bar and syn. In this order:

• Bump the version of the local syn crate.
• Bump the version of the local foo crate.
  • Update foo's dependency on the local syn crate to the new version.
• Bump the version of the local bar crate.
  • Update bar's dependency on the public syn crate to the new version of the local crate.

The last tick there is the issue. cargo ws doesn't properly disambiguate between local crates and public ones.

The branch miraclx/crate-conflict is a stage for reproducing this experiment.

Unfortunately, I think we need to implement the update logic with a proper TOML parser for this to be fixed.

Figured out a resolution for this, as well as a couple more edge cases in my fork.
