Error messaging for verification with incorrect called value could be more helpful by listing calls

[alanrussian]

Here's a sample error message:

Expected: <3>...
Expected: <3>
  Actual: <2>
Unexpected number of calls
package:test                                                                                        expect
package:mockito/src/mock.dart 666:5                                                                 VerificationResult.called

This message would be a lot more useful if it listed the interactions with the subject being verified. In this case, it could list the two calls that were made.

Good idea. In the meantime, logInvocations is another way to debug.
