dim: Fix create-branch dry run

Using --dry-run for git push on a non-existant branch (since the command
above doesn't actually create the branch) fails with:

error: src refspec topic/dim_test does not match any.
error: failed to push some refs to <remote>

So instead of using --dry-run for git push, just echo the command.

Changes in v2:
- Added comment (Daniel)
