sometimes command is null when calling sendStkResponse

[allstarschh]

Sometimes i found when calling sendStkResponse, the command argument is null.

E/GeckoConsole( 254): Content JS LOG at app://settings.gaiamobile.org/js/icc.js:13 in debug: [DEBUG] STKUI: sendStkResponse to command: null # response = {"resultCode":0,"itemIdentifier":"1"}

This seems to be caused by calling two consecutively sendStkResponse, i.e. select the menu item twice very quickly,

at lease there should be race-condition when setting iccLastCommand.

@allstarschh Can you test if these two last commits solve the issue you detected? If you agree, we can close this :)

Sure I'll try, but might need to try more times,
this issue takes a little long time to reproduce.

seems okay now,
thank you @frsela : )
