Repeated "ipcontroller" in filenames with cid in 6.2.5 #408

Traceback

Waiting for connection file: ~/.ipython/profile_default/security/ipcontroller-test-client.json
Traceback (most recent call last):
  File "<string>", line 1, in <module>
  File "/Users/gGandenberger/.pyenv/versions/ipytest/lib/python3.7/site-packages/ipyparallel/client/client.py", line 417, in __init__
    raise IOError(msg)
OSError: Connection file '~/.ipython/profile_default/security/ipcontroller-test-client.json' not found.
You have attempted to connect to an IPython Cluster but no Controller could be found.
Please double-check your configuration and ensure that a cluster is running.

Steps to reproduce

pip install "ipyparallel==6.2.5"
ipcluster start -n 4 --cluster-id=test

In a different terminal session:

python -c "import ipyparallel; ipyparallel.Client(timeout=10, cluster_id='test')"

Changing pip install "ipyparallel==6.2.5" to pip install "ipyparallel==6.2.4" resolves the problem.

Diagnosis

ipcluster is creating filenames that start with TWO instances of "ipcontroller," e.g. "~/.ipython/profile_default/security/ipcontrolleripcontroller-test-client.json".
