test_call_log_all_calls failure on v1-train

Change all-filter locator in dialer/call log app
- just a locator change

Remove delete_calls call in test_call_log_all_calls
- the indexeddb clearout deletes this for us

Also:
- move steps into test block so that if they fail the tearDown will catch them

branches:
`v1.0.1` -> do not merge
`v1-train` -> yes please, merge!
`desktop` -> untested
