Tests are not passing on the master branch

Tests should always pass on the master branch.

Reproduction

On Ubuntu, clone the bless repo. On the master branch with the latest commit: 6bef5ce, run tests:

TEST_HARDWARE=True python -m pytest -s

Below are the results:

Expected behavior

None of the tests should fail.

Desktop (please complete the following information):

• OS: Linux

Additional context
I wanted to try fixing issue #142 and launched tests as a starting point.
By fixing the test missing BlueZGattApplication parameters, more errors are raised, and the app.is_connected() method doesn't work anymore.

@EasyRiderr

Thanks for reporting this. In my last update, I failed to ensure the backend-specific tests were functioning.
