bug: Cannot use `_rlz.instance_of(list)`

See original GitHub issue

The following code now raises a TypeError

import ibis.expr.rules as _rlz
import ibis.expr.operations as _ops

class Blah(_ops.TableNode):
    test = _rlz.instance_of(list)

Blah(test=["abc"])

Traceback (most recent call last):
  File "/home/gmanoim/tmp/tmp.py", line 12, in <module>
    Blah(test=["abc"])
  File ".../ibis/common/grounds.py", line 21, in __call__
    return cls.__create__(*args, **kwargs)
  File ".../ibis/common/grounds.py", line 152, in __create__

  File ".../ibis/common/grounds.py", line 30, in __create__
    return type.__call__(cls, *args, **kwargs)
