Description

As reported by https://github.com/pedrohm in https://github.com/apache/james-project/pull/86 , the IMAP parsing layer interprets the ModSeq criterion as a flag criterion, leading to invalid searches.

We also missed some integration tests. They are impossible to write with MPT without assumptions concerning the modseq.

We can at the minimum ensure no modseq is returns for a very high modseq value.
