Fix TwoClientPrintersSyncTest.ConflictResolution.

Since https://chromium-review.googlesource.com/c/chromium/src/+/890000,
there is no implicit calls to content::RunAllTasksUntilIdle() to wait
for all pending tasks to run when GetPrinterStore() is called.

With this CL, an explicit call to content::RunAllTasksUntilIdle() is
added to TwoClientPrintersSyncTest.ConflictResolution to make sure
that both descriptions are taken into consideration and that conflict
resolution runs before expectations are verified.
