Repeated name of unit tests

[Maria Isabel Franco Trillo <mifranco igalia com>]

I'd installe jhbuild-buildbot in my machine and all seems to work, but I
realized that in "tests summary" link, in step make-check, in first
build ,after restarting master and slave, the name of the unit tests
only appears once, in second build appears twice, and so on.

I think that this behaviour shouldn't be like that.

If you have any idea or if that behaviour has to be like that, tell me
please.
