收到短信,FM外放自动切回耳机
测试步骤：
[步骤]
1.播放FM，声音选择扬声器播放
2.收到notification
[结果]
FM扬声器播放被关闭，声音转到耳机播放
[期望]
扬声器不应被关闭
2.收到notification
[结果]
FM扬声器播放被关闭，声音转到耳机播放
[期望]
扬声器不应被关闭
问题分析：
FM通过设置forceUse到SPEAKER，收到notification后系统会call setBluetoothScoOn(false)保证提示音不要从蓝牙耳机播出。
setBluetoothScoOn(false)会重设forceUse（FORCE_NO_BT_A2DP）导致提示音结束后APS选择耳机作为FM输出设备。
修改：
在当前FOR_MEDIA场景forceUse为SPEAKER时挡掉setBluetoothScoOn(false)。
