interp: do not try to interpret past task.Pause()

For context, see:
https://github.com/tinygo-org/tinygo/pull/2863#issuecomment-1133875237

Basically, testdata/goroutine.go was doing `time.Sleep()` inside an init
function which broke because doing that from a non-goroutine is not
allowed. However, we never hit this bug because of
https://github.com/tinygo-org/tinygo/issues/2842 (I didn't investigate
exactly why).
