test: provide duration/interval to timers

There are places in the code base where setTimeout() or
setInterval() are called with just a callback and no duration/interval.
The timers module will use a value of `1` in that situation.

An unspecified duration or interval can be confusing. Did the original
author forget to provide a value? Did they intend to use setImmediate()
or process.nextTick() instead of setTimeout()? And so on.

This change provides a duration or interval of `1` to all calls in the
codebase where it is missing. `parallel/test-timers.js` still tests the
situation where `setTimeout()` and `setInterval()` are called with
`undefined` and other non-numeric values for the duration/interval.
