Description:
The perfschema.hostcache_ipv6_auth_plugin fails when executed after perfschema.hostcache_ipv4_auth_plugin by the same MTR worker:

---
perfschema.hostcache_ipv4_auth_plugin    [ pass ]   5117
perfschema.hostcache_ipv6_auth_plugin    [ fail ]  Found warnings/errors in server log file!
        Test ended at 2016-08-09 05:55:10
line
2016-08-09T12:55:09.467237Z 0 [ERROR] Function 'test_plugin_server' already exists
2016-08-09T12:55:09.467268Z 0 [Warning] Couldn't load plugin named 'test_plugin_server' with soname 'auth_test_plugin.so'.
---

The opposite test order works fine:

---
perfschema.hostcache_ipv6_auth_plugin    [ pass ]   3175
perfschema.hostcache_ipv4_auth_plugin    [ pass ]    139
---

How to repeat:
Execute "./mtr perfschema.hostcache_ipv4_auth_plugin perfschema.hostcache_ipv6_auth_plugin"

Sorry, that was a result of my own change to the test.
