Keep Windows power notification handle when unregister fails

## Describe your changes
In
"TestDefaultAccountManager_UpdateAccountSettings_NetworkRangePreserved",
in the beginning of the test, during account creation a random /16
subnet from 10.64.0./10 network is used. Later in the test a new range
(10.99.0.0/16) is assigned to the account, but it's one of the possible
subnets used during account creation, which sometimes leads to a
collision and failed test.
Using a network outside of the range of networks used during account
creation fixes the issue.
