In general, slow system tests requiring no interaction from the user are
good candidates to be moved to component tests because component tests
are much faster.
In this case, the system tests were also updating the database after
starting the browser, which might cause concurrency issues. We could
split the test and have one system test per phase, but IMHO there's no
need.
We're still having a couple of system tests for the happy path, in order
to make sure users actually see the list of investments.
