This seems to fail when checking testEsniPushPart2.
The reason it's intermittent is that we clear the DNS cache when we set the TRR URI pref - that is scheduled whenever the JS pauses, so if that happens we get an intermittent failure such as this.

Assignee: nobody → valentin.gosu
Priority: P5 → P2
Whiteboard: [necko-triaged][trr]

When using add_task to schedule the tests, testEsniPushPart2 would always fail.
That's because Bug 1587875 now clears the DNS cache when the network.trr.uri
pref is changed. This is likely intermittent because of task scheduling.
This patch modernizes the test to use add_task and promises, and sets the
network.trr.clear-cache-on-pref-change;true pref so the test performs its
checks properly.
