Fail mercurialapi and qt_manifestmodel tests with python 3.11

While running Tortoisehg 6.2.x tests with Python 3.11 (for Gentoo Linux packaging) I encountered that mercurialapi and qt_manifestmodel tests are failed (see the tests log below).

The failures of tests/mercurialapi_test.py tests are due to removing of getargspec function from inspect module (deprecated sinse Python 3.10). This seems could be fixed just by replacing getargspec with getfullargspec function that available since Pyhton 3.0 (or with signature function - since Python 3.3). Both replacements solve the problem with mercurialapi tests.

Sorry, I have no idea about quick fix 3 tests failures in tests/qt_manifestmodel_test.py tests.
