[TW-178] The 'has' attribute modifier should be polymorphic, understanding dependency id/uuid

_Paul Beckingham on 2013-08-21T10:34:56Z says:_

Adding polymorphism to the 'has' attribute modifier lets us query like this:

task depends.has:22 list

This will override the substring search with something more like the Python:

if 3 in [1, 2, 3, 4]:

Note that this should work for both id and UUID values.
