Ignore line comments inside backticks

[mechanik-daniel]

When an attribute name is a URL, referring to it in expressions requires backticks.
Since the parser doesn't treat backticks as strings, it thinks everything from the // onwards is a comment

To replicate, use this input:

{
  "http://unitsofmeasure.org": "aaa"
}

And this expression:

`http://unitsofmeasure.org`

Expected:
"aaa"

Actual:

Quoted property name must be terminated with a backquote (`)
