RequestServer: Make pre-connection job refcounted

Browse source 
Fixes #22582

Previously, the job and the (cache of them) would lead to a UAF, as
after `.start()` was called on the job it'd be immediately destroyed.

Example of previous bug:

```
// Note due to the cache &jobA == &jobB
auto& jobA = Job::ensure("https://r.bing.com/");
auto& jobB = Job::ensure("https://r.bing.com/");
// Previously, the first .start() free'd the job
jobA.start();
// So the second .start() was a UAF
jobB.start();
```
