ignite-8018 : Optimized initialValue(...)
----
> Avoid unnecessary unswap(...) call in GridCacheMapEntry.initialValue(...)

> Key: IGNITE-8018

> Project: Ignite
> Issue Type: Improvement
> Reporter: Ilya Lantukh
> Assignee: Ilya Lantukh
> Priority: Major
>
> GridCacheMapEntry.initialValue(...) method executes unswap(...) to read entry
> version from PageMemory, but then it also executes storeValue(...) which
> writes new value if entry is obsolete. It means that the same entry is
> searched in PageMemory twice, which is not optimal.
