[Freeze Break] elections 2.5.1

[Pierre-Yves Chibon]

Hi all,

Elections runs into some DB troubles once in a while with a lot of queries
running.
I am not yet sure what is the root cause but one step that might already
mitigate this problem is closing the DB session after the request.

I opened a pull-request for this:
https://github.com/fedora-infra/elections/pull/41

and since it is the first change since the last release, I would like to ask for
a freeze break to cut and push a new release.


Thanks,
Pierre
