 Currently, if a plugin cannot be deleted due to plugin dependencies, it
 has a single message that shows "Note: This plugin cannot be deactivated
 or deleted until the plugins that require it are deactivated or deleted."

 The message is inaccurate in two ways - you cannot delete a plugin unless
 the plugins that require it are deleted; deactivating is not sufficient;
 and it does not reflect the current state of the plugin. If the plugin
 with dependents is already deactivated, it still states that it cannot be
 deactivated.

 Much of the structure of plugin dependencies seems to ignore whether a
 referenced plugin is active or not.

 The checks are dependent on `get_dependent_names()`, which does not
 contain any reference to whether or not a plugin is active.

 At minimum, the messages should be improved so that they accurately
 reflect what needs to happen; alternately, the messages and states should
 be matched so that the possible scenarios are reflected more accurately.
