Many modules export an `ajvCompiledJsonSchemaValidator(...)`, which
incurs the `ajv` schema compilation at module-import-time.
Many tests depend on these modules transitively, but don't exercise the
compiled schema - so, this compilation time is wasted.
On my machine, with an example test (airbrake/src/index.test.ts) I'm
seeing the following numbers (n=10):
Before: 6005.1ms
After: 5807.8ms
Benefit: 197.3ms (~3.3%)
Weirdly, the NodeJS profiler was saying that schema compilation was
taking ~2000ms, but that is likely due to the inaccuracy of the
sampling.
