[REF-2619] Reflex does not re-init when the base template changes

[masenf]

Describe the bug Prior to 0.4.7 if the reflex version that ran reflex init differs from the version running reflex run a message would be printed telling the user to re-init. This check is now missing, and template errors can result.

To Reproduce Install reflex==0.4.2 and create a new blank project.

Upgrade to reflex==0.4.8 and run reflex run.

A browser error appears.

Expected behavior Reflex automatically re-runs reflex init when needed.
