lok: remove .uno:ModifiedStatus message from deduplication mechanism

This fixes the following issue in Online:

When a save is performed while a cell is still edited the save icon
does not reflect the correct state of the document: it shows that
the document is dirty although it is not. This is generated by two facts:

1. The status cache is avoided when sending the -dirty- status right
after the cell editing is finished. Because the cache has an old value
of -false- for ModifiedStatus, the notification that is sent after saving,
with -false- value, is ignored. We should not avoid the status cache.

2. Because there is a mechanism that keeps only the last notification
value for a status change in the queue that keeps messages that were not
sent yet (deduplication), the .uno:ModifiedStatus message with a value of -true-
that is enqueued right after the cell edit is finished is replaced by the same
message with a value of -false- that is enqueued after the save is finished.
This happens if the flush mechanism doesn't occur between them.
