> we could let it work when setting _any_ attribute to an XComArg, which
would be nice
That would mean that if we set 20 attributes in `__init__` then we run
`self.set_xcomargs_dependencies` 20 times. This was the reason for the if.
But more importanlty `self.set_xcomargs_dependencies` would be called before
seeting the value for template field. For example:
```python
class DummyOp(BaseOperator):
template_fields = ("field",)
def __init__(self, field):
self.x = 42 # calls self.set_xcomargs_dependencies and fails
because selg has no attr fields
self.fields = field
```
