test: fix the plugin_exists()

in 8e61a99, we try to init the plugin when user set a profile using
"ceph osd erasure-code-profile set <profile-name> <profile>", so
if user passes in an unknown plugin, ceph will reject it right away,
instead of loading the plugin when "ceph osd crush rule create-erasure".

Fixes: #11870
