Tolerate missing or falsey substitutions (#8907)

Browse Source 
Previously the `getMessage` function would throw if a substitution was
falsey. Now it will accept any substitution, including `undefined`.

A substitution of `null` or `undefined` will still be reported to
Sentry and printed to the console as an error, but it will not
interrupt execution. Any `null` or `undefined` substitutions will be
rendered as empty strings.

Ideally we'd never pass in `null` or `undefined` as a substitution, but
in practice this sometimes just occurs breifly between renders, which
isn't a severe enough problem to justify crashing the UI.

The detection of React component substitutions has been updated as
well, to ensure that `null` values aren't counted as React
substitutions.
