Bug Description

[Impact]

Lazy imports made update-manager crash when an update-manager
update changed the backend API and an updated incompatible backend
was loaded to the not updated running update-manager process.

The issue causes crashes upon update-manager updates harming the upgrade experience for users.

The fix avoids lazy loading of the backend modules but still honors the backend selection options.

[Test Case]

1. Start with a fully upgraded system and downgrade a few packages to let u-m upgrade them:
$ sudo eatmydata apt install -y --allow-downgrades gnome-software=3.28.1-0ubuntu4 gnome-software-common=3.28.1-0ubuntu4

2. Start u-m with:
 $ update-manager --no-update

3. Make a syntax error in /usr/lib/python3/dist-packages/UpdateManager/backend/InstallBackendAptdaemon.py

4. Press "Install Now" on u-m GUI.
 The fixed u-m will successfully perform the installation, the unfixed one will fail with SyntaxError.

[Regression Potential]

Wrong changes to the backend import/selection logic could make u-m unable to find the available backends, but in my testing the fixed version could properly find both aptdaemon and synaptic when they were present.

This would also cause empty panels and hangs in the package resolver actions, I tried your upload from bionic-unapproved and put it to [1].
With that my issue is resolved as well (marekd it as a Dup)
