Subject: [PATCH] Fix filter exception when injecting CSS (PR #837)

When injecting CSS, an `onBeforeRequest paramater 'filter' must have property 'urls'` error is thrown.

![image](https://user-images.githubusercontent.com/599164/63574823-a3dd6180-c5c3-11e9-89c0-a9debdd4f696.png)

This is caused by [Electron PR #19337: Throw on invalid webRequest filters](https://github.com/electron/electron/pull/19337).

So, pass filter argument properly, like Electron expects it strictly.
