dev.open opens last url multiple times

[chasebolt]

What happened?
I have multiple urls defined for dev.open and when running devspace dev it opens the last url defined N times (N being the amount of urls defined)

What did you expect to happen instead?
To open all urls defined

How can we reproduce the bug? (as minimally and precisely as possible)
Define two urls urls and it will open the last one twice.

dev:
  open:
    - url: http://google.com
    - url: http://microsoft.com
