Describe the bug

When creating an issue using gh issue create and selecting a template, the labels associated with that template are not assigned to the issue upon creation.

$ gh version
gh version 0.7.0 (2020-04-22)
https://github.com/cli/cli/releases/tag/v0.7.0

Steps to reproduce the behavior

1. gh issue create (against a repo that has issue templates with labels associated with each)
2. Fill in info
3. Create issue without previewing in browser
4. Observe that issue was not assigned labels associated with template that was chosen

Expected vs actual behavior

If a template was chosen that has labels, those labels should be assigned to the issue when created via gh issue create

Logs

$ gh issue create
