isEnumerateCallExpression sometimes returns false when it should return true

[davidmurdoch]

I have a complex monorepo using uncompiled typescript via ts-node and ttypescript.

I've found that within the function isEnumerateCallExpression declaration.getSourceFile().fileName === indexTs may evaluate to false when it should be true.

A potential fix for this is to copy the isOurStubModule function from ts-transformer-inline-file and use it, instead, like this:

const stubModuleSource = fs.readFileSync(path.join(__dirname, 'index.d.ts'), 'utf8');
function isOurStubModule(sourceFile) {
    // Comparing of the file names may not be reliable, it doesn't work e.g. with
    // yarn's "link" resolution used in this module's end-to-end tests.
    return sourceFile.text === stubModuleSource;
}
function isEnumerateCallExpression(node, typeChecker) {
    if (!ts.isCallExpression(node)) {
        return false;
    }
    var signature = typeChecker.getResolvedSignature(node);
    if (typeof signature === 'undefined') {
        return false;
    }
    var declaration = signature.declaration;
    return !!declaration
        && isOurStubModule(declaration.getSourceFile()) // <----- HERE -----
        && !!declaration.name
        && declaration.name.getText() === 'enumerate';
}

(sorry about the JavaScript snippet, I was hacking on directly within my node_modules)

There was a similar problem in ts-transformer-keys, which has been already resolved.
I fixed ts-transformer-enumerate in the same way and released v0.5.2. Please give it a try and see if the issue is fixed.
