Remove deprecation warning

When run build **loader-utils** issued this deprecation message:
```
loader option has been deprecated - replace with "use"
(node:22316) DeprecationWarning: loaderUtils.parseQuery() received a non-string
value which can be problematic
```
So based on **loader-utils** (See: webpack/loader-utils#56)  and **babel-loader** (See: https://github.com/babel/babel-loader#options) documentation.  **options** have been removed as object and used query string instead.

Updated **fallbackLoader** to **fallback**
Updated **loader** to **use**
