fix log message for commits in the future

One-line summary

Extend log message to include the offset just compared.

Description

@tanvir002700 noted in an internal chat a situation (running Nakadi locally) where this error message is raised. When trying to look into it, I noticed that the offset printed as part of the error message is not too helpful: Nakadi is comparing offset and sentOffset, but was logging sentOffset and commitOffset.

This PR adds offset to the log message, hopefully making it easier to debug problems when this occurs.

Deployment Notes

These should highlight any db migrations, feature toggles, etc.

I didn't specifically check whether any tests are affected – looking for "will skip sending obsolete data" didn't show other locations than the one modified here, so I suppose there are no tests for this. Same for documentation.

Hm: [ant:checkstyle] [ERROR] /workspace/api-consumption/src/main/java/org/zalando/nakadi/service/subscription/state/PartitionData.java:189: Line is longer than 120 characters (found 133). [LineLength]

Wonder how it passed the build earlier? :)
