Fix default_project_creation already exists

See merge request gitlab-org/gitlab-ce!27144

For those who upgraded to a version that included the previous
backport implementation with migration 20190311132500.

The current value cannot be masked[1] but CI variables default to
masked. Rather than implementing a toggle for the masking control,
simply change the value to something that can be masked.

[1] Currently, "simple" values can be masked:
* it should be a single line
* it should not have escape characters
* it should not use variables
* it should not have any whitespace
* it should be longer than 8 characters
