Return early from ::installed_or_updated() when no plugin in list

[BrianHenryIE]

Proposed changes

When JavaScript is disabled, the plugin updater can be run with no plugins selected.

• https://core.trac.wordpress.org/ticket/61940

This results in an event which causes an error in Hiive

• https://jira.newfold.com/browse/PRESS1-427

Type of Change

Don't fire the event if there is no plugin. Return early after the WordPress action is called:

if ( ... || ( ! empty( $options['plugins'] ) && empty( $options['plugins'][0] ) ) ) { return; }

• Bugfix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• Documentation Update (if none of the other choices apply)
