test: make test-memory-usage predictable

mmarchini · targos · commit 127e2ba1ef27 · 2020-04-25T23:49:15.000+02:00
The current test relies on undeterministic behavior from V8 GC, and on newer versions of V8 this test ocasionally fails because that behavior changed. Prevent that from happening using --predictable-gc-schedule. If this test fails in the future, it should fail consistently instead of ocasionally, which should help debug.
