QS: Network Type Tile Corrections

Network Type Selection tile was not functioning correctly, unable to switch correctly between
network types.

Corrected and updated references to NetworkManager in both MobileNetworkTile and MobileNetworkTypeTile, updated QuickSettingsContainer to correctly pass NetworkManager to both tiles on creation.

Enabled TileFlip for both MobileNetworkTile and MobileNetworkTypeTile and removed unnecessary imports in MobileNetworkTypeTile.java
