Make sure plugins are not double counted

Browse Source 
In the event that a plugin with the same name was attempted to be
installed more than once, the plugin count would double count, and
result in a negative total plugin count.

This prevents actions from taking place, such as opening a popup plugin,
because it verifies that the plugin count is 0 first.
