Subject: client: manage media in session as a last step
X-Git-Tag: 1.19.3~495^2~773
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=5aec4af1b96ef5bddfc02a015e9cec3488c89f4a;p=platform%2Fupstream%2Fgstreamer.git

client: manage media in session as a last step

Once we manage a media in a session, we can't unmanage it anymore
without destroying it. Therefore, first check everything before we
manage the media, otherwise if something is wrong we have no way to
unmanage the media.
If we created a new session and something went wrong, remove the session
again. Fixes a leak in the unit test.
