NullRequestSpecs

[Bil Simser]

The NullRequest class is a bit of a placeholder in that it doesn't do
much. However in the interest of covering everything here's a spec
class for it. These could just drop into the bottom of the
RequestSpecs.cs file.

Not sure if this is value-added or not, but then if the class
shouldn't be tested then why should it be there? Inversely, if these
specs are lame what would be better ones?
