Small addition to docs

[digital-scrappy]

I added a small section to the docs that covers a problem I ran into.
Basically I did not realize that re-installing telega via Melpa would not rebuild the server so I received the minimum TDLib version warning even though the correct version was installed.

Maybe you run into the problem fixed in #221 ?

[digital-scrappy]

I don't think so. I originally had a quite old version of TDLib and the warning persisted after I had rebuilt TDLib from their git and had reinstalled telega using Melpa. Could it be that the telega-server does not get rebuilt when telega is reinstalled?.
Just to be sure I don't think this is a problem since the warning specifies that one should rebuild the server. I just thought it might be confusing to others (as it was to me) that the rebuild does not happen upon reinstall.

telega-server not necessary need to be rebuild on telega updates, only if telega-server-min-version is greater then version of the telega-server currently installed. Check your telega-server version with M-: (telega-server-version) RET and value for telega-server-min-version with C-h v telega-server-min-version RET

After updating TDLib, do not forget reloading libs cache with ldconfig, then check telega-server version with $ telega-server -h

telega should query you about telega-server rebuild if rebuild is needed, that is done by (telega-server--check-version telega-server-min-version)

If it does not, then there is some bug that should be fixed.

Could you check please, also check your telega version, because there was issue related to this, fixed in #221

[digital-scrappy]

hi my telega version is 1.7.0 and my telega-server version is 0.7.3

That is ok, you can run telega with such versions.

However, I’ve been asking for version values when you had problems and telega does not query you for server rebuild as you described in first message

[digital-scrappy]

Ah ok, sorry for not being specific, I don't know for sure what my tdlib version was (tried searching for it in my logs but did not find it). I guess the telega version must have been the same since I had just installed it that day (the 24th of December).
