[PATCH v2 05/12] t5520: test --rebase failure on unborn branch with index

Commit 19a7fcbf (allow pull --rebase on branch yet to be born) special cases git-pull on an unborn branch in a different code path such that git-pull --rebase is still valid even though there is no HEAD yet.

This code path still ensures that there is no index in order not to lose any staged changes. Implement a test to ensure that this check is triggered.

Notes:
    * Test for error message.
    
    * Ensure that when git-pull does not modify the index.
    
    * Moved test_when_finished
