* Implement last opened functionality
Fixes https://github.com/cdr/code-server/issues/4619
* Fix test temp dirs not being cleaned up
* Mock logger everywhere
This suppresses all the error and debug output we generate which makes
it hard to actually find which test has failed. It also gives us a
standard way to test logging for the few places we do that.
* Use separate data directories for unit test instances
Exactly as we do for the e2e tests.
* Add integration tests for vscode route
* Make settings use --user-data-dir
Without this test instances step on each other feet and they also
clobber your own non-test settings.
* Make redirects consistent
They will preserve the trailing slash if there is one.
* Remove compilation check
If you do a regular non-watch build there are no compilation stats so
this bricks VS Code in CI when running the unit tests.
I am not sure how best to fix this for the case where you have a build
that has not been packaged yet so I just removed it for now and added a
message to check if VS Code is compiling when in dev mode.
* Update code-server update endpoint name
