test(ci): build against dev code / fix arch issue

this will fix the build in CI for iOS at the same time it ensures
we run CI against the actual development code (vs github master, which
is what yarn installs by default)

pod install will fail on ubuntu (when building android) so allow it to fail
with the `|| true` bit, but we still install the dev code dependencies so
android tests actual dev code
