Fix dangerous File.Copy causing intermittent realm migration test failures

Browse Source 
Resolves an issue I've been able to locally reproduce on windows.
Basically, the `File.Copy` would begin while realm was blocking. The
"restore" operation is posted to the `SynchronizationContext` to run on
next update call, but in the mean time the copy would begin, causing a
conflict of interest.

Very dangerous. Only really noticeable on windows.
