chore: Add test helpers to improve coverage (#166)

* chore: Rename ProjectHistory to ProjectVersion

Version more accurately represents version storage. This
forks from the WorkspaceHistory name, but I think it's
easier to understand Workspace history.

* Rename files

* Standardize tests a bit more

* Remove Server struct from coderdtest

* Improve test coverage for workspace history

* Fix linting errors

* Fix coderd test leak

* Fix coderd test leak

* Improve workspace history logs

* Standardize test structure for codersdk

* Fix linting errors

* Fix WebSocket compression

* Update coderd/workspaces.go
