Revert of Move ChangeVersionWrapper destructor out of line.

Revert of Move ChangeVersionWrapper destructor out of line. (patchset #1 id:1 of https://codereview.chromium.org/572343002/)

Reason for revert:
No longer needed, we fixed this in clang instead (see BUG=).

Original issue's description:
> Move ChangeVersionWrapper destructor out of line.
> 
> With clang/win, the vtable of ChangeVersionWrapper ends up being referenced
> for some reason, which causes the destructor to be defined, which requires
> a definition of SQLErrorData. So move the destructor out of line, where
> the definition is available.
> 
> BUG=413478
