Arcyon: fixup 'arcyon task-*' for latest API

There have been breaking changes in the conduit API response for
`project.query`, support the new style and the old style.

Add keys that are new to project.query and maniphest.query to the ignore
list for the appropriate NamedTuples.

We'll want to look at other API changes in later work.
Closes #9
