This is mostly a direct application of the ember-angle-brackets-codemod.
I manually restored newlines in multi-line component invocations, usually
preserving file line length except for now-non-positional link-to @route.
I needed to rename task to taskState in some cases to avoid Ember
Concurrency naming conflicts.
Typically these filterable list views don't have titles beyond the
breadcrumbs, but since this page has no search bar, the title really
helps balance it out.
