t3210: add some tests of bogus packed-refs file contents

Browse Source 
If `packed-refs` contains indecipherable lines, we should emit an
error and quit rather than just skipping the lines. Unfortunately, we
currently do the latter. Add some failing tests demonstrating the
problem.

This will be fixed in the next commit.
