Add additional tests for only and all arguments for session_and_runs

[JoeZiminski]

TODO: currently only working for session and run, as well as
'all' for sessions but not for runs, is not tested. This is relatively
minor because the underlying code is shared with 'only', nonetheless
it will be necessary to add a test for this. This will necessitate adding
another toy example dataset.

[JoeZiminski]

also check that the is raised for 'all' or 'only' if they are not the only inputs to the run level.

[JoeZiminski]

also test the assert for the sessions going out of order when globbing.

Also need to test for sorting
