[Debian-med-packaging] Bug#944242: Test issues with BioPython 1.75

[Peter Cock]

There are indeed a LOT of errors in there (and a sprinkling of
harmless warnings which ought really to be silenced within the test
framework).

Picking on the very last one as a simple case, you got:

```
======================================================================
FAIL: test_ColumnUnit (test_psw.TestPSW)
----------------------------------------------------------------------
Traceback (most recent call last):
  File "/tmp/python-biopython-test.HGclMQ/Tests/test_psw.py", line 75,
in test_ColumnUnit
    "ColumnUnit(unit=0, column=33, SEQUENCE)")
AssertionError: "ColumnUnit(unit=0, column=33, kind='SEQUENCE')" !=
'ColumnUnit(unit=0, column=33, SEQUENCE)'
- ColumnUnit(unit=0, column=33, kind='SEQUENCE')
?                               ------        -
+ ColumnUnit(unit=0, column=33, SEQUENCE)
```

This change relates to adding __repr__ to some of the PSW objects,

https://github.com/biopython/biopython/commit/37f235066616c950a6b4b5544785a5c4a88f1ea1

This was included in Biopython 1.74 and 1.75, yet your copy of Tests/test_psw.py
would seem to date from Biopython 1.73 or older.

I suspect an old cached copy of the test folder is largely to blame?
