Created project for "Make project" should have default tags set

Migrated from the original issue at https://www.assembla.com/spaces/tracks-tickets/tickets/1448

When I decide to transform a todo into a projet using "Make project", the default context is set to the context of the todo. However, no default tags are set. The default tags should be taken from the todo, just as in the case of the context.
