Sitecore 10 - How to fix orphan item with Sitecore content serialization.

 It can happen when you do manual checking and miss some references.

Sitecore Error message -

Detected that item /Account (dae40400-3820-475d-a16b-ea28bb8446b7) in destination should be moved to /sitecore/content/XXXXXComponents/Header and Navigation/Navigation/Data/Account Navigation/Account, but /Account was not a path included in any serialized subtree being synced. This could indicate that a Sitecore item has been moved from its deserialized location, or that an item has been moved between two serialized subtrees where only one of the subtrees is part of the current operation. To resolve this either the serialized item should be removed (i.e. with 'pull'), or the database item moved back to the serialized tree.

Fix - Have to remove those items manually from the Serialization folder
