`quotes` not working with backticks and function string arguments

What version of ESLint are you using? eslint@2.5.3

What parser (default, Babel-ESLint, etc.) are you using? default

Please show your full configuration:

{
    "env": {
        "browser": true,
        "es6": true,
        "node": true
    },
    "extends": "eslint:recommended",
    "rules": {
        "quotes": [
            "error",
            "backtick",
            "avoid-escape"
        ]
    }
}

What did you do? Please include the actual source code causing the issue.

const foo = `Lorem`;
const bar = `Ipsum ${foo.replace("L", "l")}`;

What did you expect to happen? For the double quotes in the replace function to be valid because of the avoid-escape option.

What actually happened? Please include the actual, raw output from ESLint.

 /home/whitneyit/Code/test.js
  2:7   error  'bar' is defined but never used  no-unused-vars
  2:34  error  Strings must use backtick        quotes
  2:39  error  Strings must use backtick        quotes

Is this the intended behaviour? If not, would you welcome a PR?

I agree this isn’t a bug, and I’m not really a fan of changing the error message. Going down that rabbit hole can get very complicated very quickly, for little (if any) gain. Even if there are some unexpected situations like this that cause some research or an issue to check whether it’s a bug, in the end it all worked out and now there’s a github issue that others can learn from as well. So, personally I’m 👎 on any changes here.
