Bug#785337: "ResourceWarning: unclosed file" is emitted during the python unit tests phase of the build process

[von <matvon@mailoo.org>]

Package: python-apt
Version: 0.9.4
Severity: normal
Tags: patch

During the python unit tests phase of the build process the following warning is emitted:

/usr/lib/python3.4/unittest/case.py:577: ResourceWarning: unclosed file <_io.TextIOWrapper name=66 mode='r' encoding='UTF-8'>
  testMethod()

In tests/test_tagfile.py two files are opened and not closed. This is the reason of this warning.

The attached patch correct this problem.
