InstallabilityTester: Update the pseudo-essential cache when we remove a "choice" too
...
When we're removing choice, we need to look into all the choice groups
and invalidate the cache if it's in there.

Improve cache invalidation of (pseudo-)essential set
...
If a new pseudo-essential package was added to testing *and* it is
mutually-exclusive with an existing member, britney would incorrectly
flag it as uninstallable (unless another change triggered a cache
invalidation of the pseudo-essential set).
With this commit, the cache invalidation is now done based on whether
we add something that *might* be in the (effective) pseudo-essential
set. It is an overapproximation as there are cases where the
invalidation is unnecessary, but at the moment it is not a performance
concern.

This commit updates the test suite to use the BinaryPackageUniverse
instead of the InstallabilityTester where that makes sense. The rest
of Britney has yet to be updated except where absolutely necessary (as
that will come in a later commit).

The InstallabilityTester is suffering from a lack of clear purpose
because it serves multiple. This commit extracts most of one of these
