Add page doesn't have context/project suggestions if visit directly or too fast

[bobwhitelock]

Only has default contexts, which are hard coded. Presumably as request for tasks hasn't finished at the point tribute is initialised. Might be fixed by #65 as loading is moved to router there.

Would still be annoying to wait for tasks to load to be able to create a task (or to have auto-completion when creating a task), would be good if tasks were saved in local storage so could access past contexts/projects immediately
