[BUGFIX beta] Improve error for improper invocations of link-to.

[nathanhammond]

Unfortunately, to get decent error messages, we need to do something like this. In some future state we should be able to use a "feature flag" which allows us to strip this without needing to call it twice.

if (isProdBuild()) {
  // Do the useful debug thing, probably including try/catch.
} else {
  // Do the performant thing.
}

I believe either the truthy/falsey blocks should be flip/flopped or this conditional should be changed to isDebugBuild() (since we want to do the most performant thing in prod mode)...

[nathanhammond]

Definitely wrote the wrong thing. Adjusting.

This looks great, I have visions of threading through the callsite information so we can show template module name and line number info as well, but this is a great improvement already.

[rwjblue]

LGTM, definitely a better error message than the default one...

[nathanhammond]

@rwjblue Note that the error, by including e.message, also includes the name of the segment that you didn't pass in via tildeio/route-recognizer#116. 😄

[nathanhammond]

K, we're good here.

Awesome, thank you @nathanhammond!
