Bug 26231: Remove incorrect use of AddAuthority() when 001 present

Bug 26231: Remove incorrect use of AddAuthority() when 001 present

This patch removes the use of AddAuthority with a non-empty
authid argument, since that triggers an update rather than an insert.

In practice, the update also fails, but the error isn't raised,
as the database connection doesn't have RaiseError set.

Test plan:
1) Do not apply patch
2) Try to bulkmarcimport an authority file with a 001
3) Observe that the script reports success but no authority is added
4) Apply the path
5) Try to bulkmarcimport an authority file with a 001
6) Observe that the script reports success and the authority is added
