failing test for no-unreachable

[mightyiam]

Please provide pointers on solving this.

eslint/typescript-eslint-parser#127

[j-f1]

Looks like the code responsible for setting this type is:

lib/convert.js:610

/**
 * Prefix FunctionDeclarations within TypeScript namespaces with "TS"
 */
if (node.parent && node.parent.kind === SyntaxKind.ModuleBlock) {
    functionDeclarationType = AST_NODE_TYPES.TSNamespaceFunctionDeclaration;
}

closing this as it was a bug in the parser
