Description of problem:
When creating the first version for a new project, the copy version kicked in,
but there is no version to copy from, so it stuck there.

Version-Release number of selected component (if applicable):
Zanata 3.5.0-SNAPSHOT (git-jenkins-zanata-server-github-pull-requests-1943) 

How reproducible:
Always

Steps to Reproduce:
1. Login
2. Create a new project
3. Create a new version
4. Go to the newly created project-version view

Actual results:
The version was readonly.

Expected results:
The version should be writable.

Additional info:
The workaround is mark the version as writable.

However existing users like me are quite likely not aware of this new behavior and wonder why the push failed; and new users would think this is a bug of Zanata that you cannot push the first version.

Thus I put severity as high.
