Update hasEverConnected for wifi networks

Set hasEverConnected to true for a network that completes a connection.

Set hasEverConnected to false when a network config changes.

Add tests to confirm hasEverConnected was added on a successful
connection and cleared when connection or credential related
configuration changes are made.

Also removed some unused imports to fix checkstyle issues in
WifiStateMachine and WifiConfigStore.
