[Fix] Compilation error when method name is string instead of identifier

[shijistar]

I got a compilation error when a component method name is string instead of identifier. The sample code is,

class MyComponent {
    "special-method-name"() {
        // ...
    }
}

Normally method names should be valid identifiers. However for some reason, I need one of my methods must be in a special form. Eslint raises an error, but babel goes well and the code works well in chrome too.

The difference between Identifier and String method is that the node.key.type is Identifier/Literal. If method name is Identifier, the node.key.name is the identifier name, however if method name is String, we should get the method name by node.key.value.
