smp server: fix missing web page information
PR #1608 introduced a bug that made only some of the information about the server generated on the web page.
what problem does it solve? Specifically, what set of data in INI file would make the page missing? The intent of the code you removed is to collapse the sections that have empty strings as data - I've not seen it resulting in page missing.
Please go to a smp server web page (let's say smp6.simplex.im). If you look closely you'll see that there is no commit indication next to the version number. There is also a bunch of other stuff that is missing like the contact info of the administrator (which you suggest to set always). I noticed it because I set an administrator simplex contact on my own smp server but it wasn't showing no matter what.
Speaking of the code: I simply reverted those lines to the very previous version that worked before and it worked! The newer version of the code didn't seem to only collapse the sections that have empty strings but to somehow collapse other stuff.
