Bug#1058967: python-biopython: please remove extraneous Build-Dep on python3-unittest2

[Alexandre Detiste]

Source: python-biopython
Severity: normal

Dear Maintainer,

python3-unittest2 was a backport of Python3's standard "unittest" to Python2.

Upstream is now using the real thing.

Please remove the override from debian/control.

Greetings,
