Add schema cache to new connection pool after fork

Active Record detects when the process has forked and automatically
creates a new connection pool to avoid sharing file descriptors.

If the existing connection pool had a schema cache associated with it,
the new pool should copy it to avoid unnecessarily querying the database
for its schema.

The code to detect that the process has forked is in ConnectionHandler,
but the existing test for it was in the ConnectionManagement test file.
I moved it to the right place while I was writing the new test for this
change.
