Fix tree-view sticky headers of one-dark & one-light themes

[asiloisad]

The fixes of sticky headers are outdated and it generate some bugs now, like:

• Sticky projects headers make clicking the item above a selected folder impossible atom/one-dark-ui#257
• More sticky header fixes atom/one-light-ui#133

I have just deleted old fixes and everything looks working perfectly...

Thanks a ton for the PR! I'll have to test the binaries out once they are built and see what this does, but appreciate the contribution

@asiloisad So I hate to say, I've tried taking a look at this one a couple of times, and while I'm not seeing any negative effects of the change, I also can't replicate the issue it aims to be fixing either.

I've gotten with another maintainer who also can't replicate it. I'd love to be able to get your fix in, but would you mind detailing any steps on how to replicate the issue or maybe even a before after of this change fixing it for you? Since even if an edge case, obviously we want things to function as well as possible for everyone

At picture there is short tutorial how to reproduce the bug. I have test it with brand-new .pulsar.

I was able to replicate it with the above instructions. It looks like it indeed relates to this padding:

[asiloisad]

A strange padding has been introduced by fixes deleted in this commits. They were written to fix auto-revealed, but after deleting them I am not able to get any error related to it.

With the additional steps to replicate, and @Daeraxa helpfully testing, can confirm this fixes the issue at hand, and doesn't seem to reintroduce the issue it originally aimed to fix.

Thanks a ton for the contribution @asiloisad and let's get this one merged!
