Updated tests: cases with bugs or which cannot be run
with the cursor-protocol were excluded with
"--disable_cursor_protocol"/"--enable_cursor_protocol"
Fix for v.10.5
This is an addition to original fix. Buildbot revealed another sporadic failure
in perfschema.threads_mysql test. Tests relies on data stored in
performance_schema.threads, while performing waits on
information_schema.processlist. These tables are not updated synchronously.
Fixed by performing waits on performance_schema.threads instead.
