fix: PkgResourcesDeprecationWarning from mopidy/ext.py

[Simon-the-Sorcerer]

sry for creating a new PR. I'm only a little server admin and rebasing was too scary 😉.

I changed the base branch to release-2.2 and started again.

Lovely to find a PR with a fix just hours after I created the issue! :-)

A couple of comments:

According to this setuptools commit the new methods where added in setuptools 11.3 about five years ago. According to packages.debian.org, Debian oldstable (stretch) ships setuptools 33. In other words, we can safely remove the if hasattr(...) and instead assume the "new" API to be present.

Second, some tests in tests/test_ext.py are failing. It seems you simply need to update a mock definition ~3 places:

-mock_entry_point.load.return_value = DummyExtension
+mock_entry_point.resolve.return_value = DummyExtension

Lastly, please rebase the fix on top of the release-2.2 branch and make that branch the basis for the PR. That way we can ship the fix in the next 2.2 bugfix release. The develop branch will not be shipped until Mopidy 3.0 is ready.

Thank you! :-)
