Command "add addin|tool|module from NuGet" removes additional query params

Given the following setup:

(Notice how version and package are "switched" in `Cake.7zip`)

When I run the "add addin from NuGet" command and re-select `Cake.7zip` (i.e. to update the version), the line will look like this:

(Notice how package and version now follow the "usual" ordering).
Which is fine for me. (Not 100% optimal, but "ok".)

However, is the setup would be something like:

after re-running the command, the line will look like this:

Which is a problem, when the additional params were needed for something. (I.e. if one of the additional params was `loaddependencies=true`...)

Reproduce the "add addin|tool|module from NuGet" command with a package entry containing additional query parameters such as loaddependencies=true. Trace the command's NuGet entry handling to find where the entry is rewritten; done means updating the package or version preserves all existing query parameters.
