Unittests are failing on new clone

[zysoddev]

Hello!

I just cloned the repo to create a feature branch. Running pytest on the base branch fails with the following error.

plyer/platforms/linux/uniqueid.py:35: IndexError
================================================================= short test summary info =================================================================
FAILED plyer/tests/test_notification.py::TestNotification::test_notification_notifysend - AssertionError: 'NotifySendNotification' not found in '<plyer....
FAILED plyer/tests/test_uniqueid.py::TestUniqueID::test_uniqueid - IndexError: list index out of range
============================================================== 2 failed, 35 passed in 0.51s ===============================================================

Is this expected?
