Revert logical snapshot filename format change in SnapBuildSnapshotExists().

Browse Source 
Commit 2633dae2e48 standardized LSN formatting but mistakenly changed
the logical snapshot filename format in SnapBuildSnapshotExists() from
"%X-%X.snap" to "%08X-%08X.snap". Other code still used the original
"%X-%X.snap" format, causing the replication slot synchronization worker
to fail to find existing snapshot files and produce excessive log messages.

This commit restores the original "%X-%X.snap" format
in SnapBuildSnapshotExists() to resolve the issue.
