Tomasz Grabiec e90449f770 test_tablets_parallel_decommission: Fix flakiness due to delayed task appearance ...

Currently, the test assumes that when
'topology_coordinator_pause_before_processing_backlog: waiting' is
logged, the task for decommission must be there. This was based on the
assumption that topology coordinator is idle and decommission request
wakes it up. But if the server is slow enough, it may still be running
the load balancer in reaction to table creation, and block on that
injection point before decommission request was added.

Fix by waiting for the task to appear rather than the injection.

Fixes SCYLLADB-715

(cherry picked from commit d33d38139f)
