Set the following compiler defaults:
```
"target": "es6",
"module": "commonjs",
"moduleResolution": "node",
"sourceMap": true,
```
Which allows us to not even include a tsconfig.json file. If one is
present, `ts-node` will use its options, but the above settings will
override any settings in a local tsconfig.json file. This means if you
want full control over the target, you'll need to go back to the raw
tsc workflow where you explicitly build ahead of time.
We retain a few tests on the RunBuild plan, with `typescript` set to
false in the runtime options, but for the general case, we remove the
build steps and custom entry points for our programs.
The two-phase output properties change broke the ability to recover
from a failed replacement that yields pending deletes in the checkpoint.
The issue here is simply that we should remember pending registrations
only for logical operations that *also* have a "new" state (create or
update). This commit fixes this, and also adds a new step test with
fault injection to probe many interesting combinations of steps.
