Administration: Guard against `false` transient key in `get_cached_events()`. 

Inside `WP_Community_Events::get_cached_events()`, `WP_Community_Events::get_events_transient_key()` is used to retrieve the transient key name, based on the user's location.  However, the transient key can potentially return `false`, resulting in a call to `get_site_transient()` with the `$key` being `false`.

This change first attempts to evaluate and guard against a `false` return from `WP_Community_Events::get_events_transient_key()`.  The result is an early `false` return from `WP_Community_Events::get_cached_events()`.
