Fix precompile

[karthik2804]

This PR fixes an issue discovered by @kate-goldenring. The default template without a router failed to compile because it did not have any regex, and the return of precompile was a string rather than an object. This PR gives the precompile function a consistent return type.

Can we add a test for this by any chance? Other than that, LGTM!

@tschneidereit I added a test but now realize it is going to fail until we have a new release as I added it to the template test . Do we want to do that or just add a new test that points at the latest build of the tools?

The more I think the more I feel like I should do the later as well as testing the templates can be run successfully.

Yeah, I think that's what we should do: in general we should be able to test changes before releasing them, instead of having failing tests that can only be fixed with a release. If we're doing the latter, we always run the risk of having some other issue causing the test to fail, which is hidden until we do the release.
