` Construct a testset on the master node which will hold results from all the
test files run on workers and on node1. The loop goes through the results,
inserting them as children of the overall testset if they are testsets,
handling errors otherwise.
Since the workers don't return information about passing/broken tests, only
errors or failures, those Result types get passed `nothing` for their test
expressions (and expected/received result in the case of Broken).
If a test failed, returning a `RemoteException`, the error is displayed and
the overall testset has a child testset inserted, with the (empty) Passes
and Brokens from the worker and the full information about all errors and
failures encountered running the tests. This information will be displayed
as a summary at the end of the test run.
If a test failed, returning an `Exception` that is not a `RemoteException`,
it is likely the julia process running the test has encountered some kind
of internal error, such as a segfault. The entire testset is marked as
Errored, and execution continues until the summary at the end of the test
run, where the test file is printed out as the "failed expression".
