parserConfiguration "strip-aliased" causes "coerce" not be applied for expanded-camelcase

```bash
$ node -e 'const p = require("yargs")(["--n-e", "1"]).option("n-e", { coerce: n => n + 1}).parserConfiguration({ "strip-aliased": true }).parse(); console.log(p)'
{ _: [], 'n-e': 2, nE: 1, '$0': '' }
```

without is ok
```bash
$ node -e 'const p = require("yargs")(["--n-e", "1"]).option("n-e", { coerce: n => n + 1}).parse(); console.log(p)'
{ _: [], 'n-e': 2, nE: 2, '$0': '' }
```
