devtool: make find-recipe and edit-recipe always work with any recipe
After some reconsideration I think it's a bit annoying for users to be
forced to use an option to work with recipes where the file isn't in the
workspace, so let's just have these commands check the workspace first
for the recipe, and if it isn't there then load the cache and get it
that way.
