`testConfigurations` expects at least one configuration, so avoid
calling it when there are no configurations.
This fixes the unhandled exception with `test_runner.dart --help`:
```
No build targets found.
Unhandled exception:
RangeError (index): Invalid value: Valid value range is empty: 0
<asynchronous suspension>
```
With this commit, `--help` just prints "No build targets found" and
exits with 0.
This crash was previously fixed in
02a0396f74.
