Description:
------------
an exception is thrown and a warning is emitted if no result is available.
There is no need to emmit this!!!

With this (change due to @ operator) it makes db handling more complex without any benefit. Since insert/update events do not have any results.

Expected result:
----------------
do NOT emit any warning! this causes error checks to trigger, which is not desireable!!!

Actual result:
--------------
an exception is emitted (can be handled, but unneeded)
and a warning is emitted which is worse, since it can't be silenced!

> Since insert/update events do not have any results

and why would you then free the result?
be happy that php tells you a useless function call

in 99.9% of all cases you can remove 100% of mysqli_result::free from your codebase at all
