Don't pop if not redirecting from MODAL session

Fixes #190.

This PR also resolves a redirection animation issue I've encountered while testing the v1.3.0 beta.
Before v1.3.0, redirecting to the previously visited URL would result in popping the view controller with an animation. In v1.3.0 beta, this animation is missing.

v1.2.2 behavior:

v1.3.0 beta behavior:

This PR restores that pop animation 🎉
Thank you @joemasilotti.
