generate:bundle is defaulting to the cache directory in 2.3.14, 2.3.15 and 2.4.5 

In 2.3.14, 2.3.15, and 2.4.5, when I run `php app/console generate:bundle` I get the following prompt:

```
Target directory [/home/intrepion/path/app/cache/dev/../src]:
```

But when I revert back to 2.3.13 or 2.4.4, I get exactly what I expect:

```
Target directory [/home/intrepion/path/src]: 
```
