IMPALA-12916: Fix test_event_processor_error_global_invalidate test random
failure
Event processor goes to error state before it tries to global invalidate
It remains in error state for a very short period of time. If
wait_for_synced_event_id() obtains event processor status during
this period, it can get status as error. This test was introduced
with IMPALA-12832.
Testing:
- Tested manually. Added sleep in code for testing so that event
processor remains in error state for little longer time.

> EventProcessor goes into the ERROR/NEEDS_INVALIDATE state when it hits
> unexpected failures in processing an event. The cause are usually bugs. When
> it stops, all tables that need sync will be impacted. However, the event
> might just a single-table event (in contrast to multi-table events like
> RenameTable, DropDatabaseCascade, CommitTxn, AbortTxn). We can consider
> skipping the event and just invalidating the table.
