[This commit](2503464)
changed the way we detect the context for fetching the `let_it_be`
defined variables, matching only the `before(:context)`. Those variables
should be accessible by both before/after, so this adds back the generic
`:context` matcher to support all hooks.

…or minitest.

When the test suite is run in parallel, the run method only enqueues the
test jobs and returns right after that, so we mustn't roll back the
transaction at that point.
Instead, intercept the Minitest.run_one_method call that actually runs
a test case. In each process, we will keep track of when the last test
case of a test file has run, and roll back the transaction in that moment.
This works because test cases from different test files are added to
the queue and processed in order, i.e. once we see a test case from a 
different class/test file, no test cases from the previous test file will
be run anymore.

…tests

parallelize_teardown allows registering callbacks that are run after
parallel test execution. It is called after all tests are run and before
the forked processes are closed, so we can use it to clean up the last
of the before_all transactions.

This is to ensure that if tests were run in parallel, that values would
not override each other/be used from other threads.

For an application with multiple databases, allow the databases not-under-test to not be running (not connectable) and for before_all to still work.
