"Component tplink unable to import" Travis CI config file checking broken in 0.94.4 worked in 0.94.3

[shortbloke]

Home Assistant release with the issue: 0.94.4

Last working Home Assistant release (if known): 0.94.3

Operating environment (Hass.io/Docker/Windows/etc.):
Travis CI - Xenial - Python 3.6 and 3.7

Component/platform:
tplink

Description of problem:
I use TravisCI as part of ensuring my published configuration is fully working. As of 0.94.4 this has broken with an error for each of my packages which contain the tplink component, "component tplink unable to import"

 homeassistant.packages.appliance_dryer.tplink: 
    - Package appliance_dryer setup failed. Component tplink unable to import

Final output from Travis

Successful config (partial)
  homeassistant.packages.appliance_dishwasher.tplink:
  homeassistant.packages.appliance_dryer.tplink:
  homeassistant.packages.appliance_irons.tplink:
  homeassistant.packages.appliance_washingmachine.tplink:
The command "hass -c . --script check_config" exited with 4.

Problem-relevant configuration.yaml entries and (fill out even if it seems unimportant):

Still broken in 0.95.4

Same here. Works perfectly fine on my docker based installation at home but fails on travis.

# python -m homeassistant --config /config --script check_config
Testing configuration at /config

Still seems to be an issue with TPLINK with 0.95.4

@CCOSTAN That's expected the change was merged to dev 10 days ago (7 July). 19.4 was released on 28 June.
So we just need to await the next release to pick up the change.

Aah! Perfect. I wasn't sure how this was incorporated into the release cycle since it was travis. Thanks!
