brace-style error when try/finally block is missing a catch block

[bressain]

The brace-style rule throws when it encounters a try/finally block with no catch, e.g.

try {
  // do some stuff here
} finally {
  // clean-up code here
}

Adding the catch block fixes the problem.

The error is something like:

/node_modules/tslint-eslint-rules/dist/rules/braceStyleRule.js:130
        return node.getSourceFile().getLineAndCharacterOfPosition(node.getEnd());
                   ^
