MDEV-21025 Server crashes on START TRANSACTION after INSERT IGNORE (#1489)
If a transaction had no effect due to INSERT IGNORE and a new
transaction was started with START TRANSACTION without committing
the previous one, the server crashed on assertion when starting
a new wsrep transaction.

As a fix, refined the condition to do wsrep_commit_empty() at the end
of the ha_commit_trans().
