add basic cargo test support #4

not sure if this is what the ticket is referring to, but it seems like the zome generation currently has the wrong cargo versions - i'm getting 

failed to select a version for `serde`.
    ... required by package `holochain_json_derive v0.0.21`
    ... which is depended on by `entry v0.1.0 (project/zomes/entry/code)`
versions that meet the requirements `= 1.0.100` are: 1.0.100

all possible versions conflict with previously selected packages.

  previously selected package `serde v1.0.89`
    ... which is depended on by `hdk v0.0.42-alpha5`
    ... which is depended on by `hdk_proc_macros v0.0.42-alpha5`
    ... which is depended on by `entry v0.1.0 (/Users/drew/coding/meta/holo-core/zomes/entry/code)`

failed to select a version for `serde` which could resolve this conflict
Error: Couldn't traverse DNA in directory "project": command

so adding basic cargo version tests would prevent this, or let someone know they're out of date.

Anyone know where i can find the most recent version of these packages?

@DrewMcArthur unfortunately the issue is a bit more subtle than that

the thing that consumes the scaffolding currently is a rust binary that follows the release cycle of the holochain conductor itself

tied into that repository is the HDK that also follows the same release cycle

whatever is pushed out by this scaffolding and the HDK need to line up.. but also we have a QA process where we don't put new versions of what comes from the upstream binary build process into the "love" (fully QA'd and released and ready for general consumption) branch in holonix downstream

this means that we don't have a way at the moment of making a version of hc and the HDK separately such that we can manage the scaffolding to service both simultaneously across dependency upgrades

i think the way to resolve this is to not have HDK, hc and holochain all locked to the same release process and cycle, and depencency graph, so the scaffolding can track HDK depencencies without worrying about what holochain might need

hAppy tam has built a holonix scaffold.
