TestArgcomplete.test_complete_custom_completers fails with 3.12.7

[mcepl]

With the upgrade to 3.12.7 tests started to fail, most likely because of large changes to argparse module:

This should be the same issue as kislyuk/argcomplete#507, I assume the fix in argcomplete should be relatively straightforward, this test could be temporarily skipped in the meantime if its blocking anything.

still seems broken but the (reverted) patch at kislyuk/argcomplete#513 fixes.
