It load assets by Pack with json data. - Without dataKey, it works fiine - With datakey `test1`, it won't work. It might because that, [redundant reading dataKey in JSONFile loader](https://github.com/photonstorm/phaser/blob/v3.60.0-beta.4/src/loader/filetypes/JSONFile.js#L77), therefore [this.data](https://github.com/photonstorm/phaser/blob/v3.60.0-beta.4/src/loader/filetypes/PackFile.js#L65) will be incorrect.
