Simple quick fix for #1418

[sapk]

@Morlinest detected in #1418 a bug introduced in #1389.

This is mainly cause because I didn't catch impact on hooks pages and sub .menu item of .list

For .menu I use > parent link to fix sub .item catch.
And for hook remove specific code that interfere with global style.

This is a quick and "simple" fix and more work can be done to use less css hack and use class from semantic like .divided in place of :not(:first-child). This is done in #1450 and a progress is allready done in #1435 by @Morlinest

So what's the different this from #1435 and #1450 ?

[sapk]

#1435 just fix branch by changing aspect because before the have had a update button as large as the page. That what king of "ugly" and by changing that also fix by removing use of .list (that useless because not a list)

#1450 Is going further by removing a other css hack :not(:first-child) that apply top border for list but that useless because semantic have a .divided class that does the same. But that imply to check for all .settings pages that include a .list. Implementing this would also fix the bug that I introduce.

This PR is more of a simple&quick fix that ready to be apply.
