so we can use sed to edit it when executing functional tests in docker
with gitlab-ci

it matches what the scheduler would use. But we still need to check for
"DONE" since it currently exists in the database.

when changing the config for launching a run we wait for a query. So we
also need to query the table again

It would seem that we use "DONE" to indicate a pre_process has
completed rather than "COMPLETED" as for scheduler tasks.

jstree keeps its state so we only need to open the root folder if it is
closed

Since all our tables have the same id we need to ensure our queries have
completed before attempting to see if the new table has loaded.

It would seem that sequence_file.data_file cannot be unicode, so we need to cast it to
str.

ensure that field ids match between the server side and the js-generated
form fields.

Since I'm bad, we need to enforce an order in the test file execution.

This was another thing matching the newer way of doing things in Watir,
but we use an older version

sometimes the test will fail because the DOM hasn't fuly loaded, so we
need to wait for the table line we want to be present

Since we use an old version of watir for our tests, we need to use the
old way of doing things :)

for the call to Watir::Wait.until simply pass the timeout value instead
    of passing a named parameter

$1 is only the first parameter thus launch_functional_tests usage was not
clear. Instead we use $*.

(not currently working)

preserve the edited patient in order to apply the filter on its info.

reorganise the server functional test files to match the browser
functional tests

Patients are sorted in reverse order of creation, so we should expect
the last patient created when clicking on the first row.
