Selecting .taskrc in 'Configure Taskserver' isn't picking up the `recurrence=off` line

If I select a .taskrc for the app to read, the config lines that then display in the app aren't showing my `recurrence=off` line.

I am seeing my taskd.server and taskd.credentials lines but not the `recurrence=off` line.

Start at the “Configure Taskserver” flow and trace how a selected .taskrc is parsed and its configuration lines are displayed. Reproduce the issue with taskd.server, taskd.credentials, and recurrence=off entries; done means recurrence=off appears in the app alongside the other selected configuration lines.
