Fix installation activation bug
What does this MR do and why?
There is a bug when attempting installation's auto activation, and if connectivity issue occurs, a NoMethodError would be raised. This is because the errors can sometimes be a string instead of array.
How to set up and validate locally
- Stop CDot if it is already running
- Create a cloud license subscription on CDot, and obtain its activation code
- On SM instance, run
bundle exec rake gitlab:license:load GITLAB_ACTIVATION_CODE=foobar
The result should print out CONNECTIVITY_ERROR without ruby exception.
