CodeceptJS 3.7.x: "tryTo" and "session" do not work together

[danielrentz]

In CodeceptJS 3.7.x, using the tryTo effect inside a session makes a test hang forever. This works as expected in v3.6.10 with the old global tryTo plugin.

Simple example:

import { tryTo } from "codeceptjs/effects";

Scenario("[SESSION1]", async ({ I }) => {
    await tryTo(() => {
        I.say("SESSION1");
    });
});

Scenario("[SESSION2]", async ({ I }) => {
    await session("SESSION2", () => {
        I.say("SESSION2");
    });
});

Scenario("[SESSION3]", async ({ I }) => {
    await session("SESSION3", async () => {
        await tryTo(() => {
            I.say("SESSION3");
        });
    });
});

The third test case "SESSION3" will never end.

As far as I can tell from debugging inside the CodeceptJS source code, the root cause is that both session and tryTo want to start a new session via recorder.session.start(). But inside this function, an existing session is considered to be an error, and the outer session will be reset.
