[autotest] Provide suggestions when test_that failed to locate any test.

Make it easier for user to locate the exact test to run. When test_that failed
to locate any test matching the test argument, provide a list of suggestions.
For example:

test_that -b peppy   --fast 172.27.213.193  e:dummy_Pass_123

leads to following exception message:

ValueError: Found no tests. Check your suite name, test name, or test matching wildcard.
Did you mean any of following tests?
  dummy_Pass
  dummy_PassServer
  dummy_Pass.wifichaos
  dummy_Pass.actionable
  dummy_Pass.experimental
  dummy_Fail
  dummy_Pass.bluetooth
  dummy_RepeatArgs
  dummy_FailServer
  dummy_FailServer_Flaky

BUG=chromium:441455
TEST=local test runs with test_that:
test_that -b peppy   --fast 172.27.213.193  e:dummy_Pass_123
test_that -b peppy   --fast 172.27.213.193  f:dummy
test_that -b peppy   --fast 172.27.213.193  suite:bvt_123
