Pack succeeds for an invalid yaml (which fails to upload anyway)

[sed-i]

Bug Description

I renamed a plug following this recommendation, but forgot to update the plugs section under apps.

With this, snapcraft pack succeeds, but uploading rightfully fails, with:

• interface 'dot-config' not found in base declaration
• unknown plugs interface name reference 'dot-config

Snapcraft pack should probably fail on a linting issue such a this?

To Reproduce

Run snapcraft pack on this revision.
