Remove dummy if statements

[shadowspawn]

Pull Request

I was using an if statement for a block in the type tests like:

if ('test description') {
   ....
   expectedType(...);
}

to mirror the Jest test layout:

it ('test description') {
   ....
   expect(...);
}

Problem

TypeScript started complaining about the truthy value (string) used for the if expression.

Solution

Move the test description to a comment. Keep the blocks so have scoped local variables.
