This problem surfaced due to a recent change that makes the rill project refresh trigger parser refreshes in addition to the usual source and model refreshes.

The problem is that the parser always writes model specs with trigger == false, which may override a concurrent refresh trigger that has just set trigger = true.

I will add tests to cover this issue in a follow up PR.
