Stop auto load installed plugins tab

[Hưng Thành Nguyễn]

Currently, in plugins pages. When I finish installing a plugin nodebb auto load back the installed plugins tab to activate the plugin.
This is annoying. I can activate later after I install a bunch of plugins.
I suggest to stop load back the installed plugins tab. Just let the user decide when they should activate the plugins.

@Hưng-Thành-Nguyễn I can argue that it should be left as is. The only time I can think of when you will be installing a "bunch" of plugins is when you are setting NodeBB up initially. After that... I don't see a use case where you will be installing so many plugins at once.

So keeping it as it is makes sense for most cases.

Bad idea to batch install plugins.

If ones not compatible with your version of nodebb, you're in for a world of hurt diagnosing which plugin is giving you issues.
