(CANTINA-949) Jetpack: Move pre_option_jetpack_active_plan around to run before JP loads

[rebeccahum]

Description

Fixes the issue of modules being deactivated by check_plan_deactivate_modules(). Also, removes Jetpack::is_active() check in the option filtering since it calls get_userdata() which isn't available at that point of code execution.

Changelog Description

Plugin Updated: VIP Jetpack

Fixes the issue of modules being deactivated by check_plan_deactivate_modules().
