Test fail with python-3.10

[mikelolasagasti]

I packaged pg_activity for Fedora and as future Fedora-35 will have python-3.10 some tests are being done already.

tests fail with python-3.10 as reported downstream and also with travis

It seems repr order of flags changed in python/cpython#24215 to follow definition order.

Python 3.8 : <Flag.APPNAME|DATABASE: 3>
Python 3.10 : <Flag.DATABASE|APPNAME: 3>

Failure of pgactivity/types.py::pgactivity.types.Deserializable appears to be due to a change in python-attrs about the type attribute of attr-classes' fields:

python3.10:

>>> @attr.s(auto_attribs=True)
... class X:
...   y: int
... 
>>> attr.fields(X)[0].type
'int'

python3.7:

>>> @attr.s(auto_attribs=True)
... class X:
...    y: int
...
>>> attr.fields(X)[0].type
<class 'int'>

EDIT: more details at python-attrs/attrs#716

>>> attr.resolve_types(X)
<class '__main__.X'>
>>> attr.fields(X)[0].type
<class 'int'>

In any case, test failures seems to be due to assumptions made in tests which are now invalid; so I suppose the program would still work as expected. I'll look into fixing tests, though.

Thanks for the report and for your packaging and QA effort!

All tests are fixed on Python 3.10 now, and a version 2.1.2 just got released.
