Use reporter extended consistently. (#145617)

Shard tests present output inconsistently using the compact or extended reporter depending on the defaults of flutter test and dart test. To make the output consistent and simplify debugging of failures this PR is enabling the extended reporter for all the tests based on unit/integration test packages.
