When doing something like :
```
from metaflow import project
....
mymutableflow.add_decorator(
project, deco_kwargs={"name":"abc"})
```
Metaflow breaks with the error :
```
File ".../metaflow/flowspec.py", line 312, in _process_config_decorators
deco.pre_mutate(mutable_flow)
File "mydeco.py", line 67, in pre_mutate
mutable_flow.add_decorator(
File ".../metaflow/user_decorators/mutable_flow.py", line 409, in add_decorator
_add_flow_decorator(
File ".../metaflow/user_decorators/mutable_flow.py", line 353, in _add_flow_decorator
d for d in self._flow_cls._flow_decorators if d.name == flow_deco.name
^^^^^^
AttributeError: 'str' object has no attribute 'name'
```
This is because we dont parse the _flow_cls._flow_decorators in the right way (as a dict instead of list)
