George Kalpakas 3b7a571cc5 test(upgrade): clean up global state after test (#28181)
In ngUpgradeLite, when a downgraded component
[requests its downgraded module][1], the AngularJS injector is
[temporarily stored][2] with the intention of grabbing it
[once the module has been bootstrapped][3] (which also cleans up the
[temporary injector reference][4]).

In [some tests][5], bootstrapping a component might throw an error,
which causes the test to fail immediatelly and move on to the next
test. In slow browsers (e.g. on CI/Saucelabs), the (successful)
bootstrapping of another downgraded module might not have been
completed in time and thus the temporary injector reference not cleaned
up.

In such a case, if the following test (in our randomized test suite)
happens to rely on the temporary injector reference's being initially
unset (such as [this test][6]), it will fail. This might appear as a
flake on CI, because it depends on a race condition and specific order
of tests, so it usually goes away after a rerun.

This commit fixes it by ensuring the temporary injector reference is
manually cleaned up, when necessary.
