After opening settings app if the user taps on cellular & data too fast the SIM settings menu will not be displayed.

This issue can be reproduced both manually and with automation:
Repro rate: 5 out of 5

1. open settings app and tap on "Cellular & Data" without waiting
2. navigate through the settings menus then back to "Cellular & Data"

Expected results:
While in the "Cellular & Data" menu the SIM settings options should be displayed.

Actual result:
SIM settings are missing and do not load even after navigating back and forth (screenshot attached).

The only way to load the SIM settings is to close and re-open the settings app and wait ~5 seconds before tapping on "Cellular & Data".
This was tested on Flame devices, 319MB v188-1 Shallow Flash

it looks like this was caused by Bug 1092104
Assignee: nobody → arthur.chen
The root cause is that it accesses to a variable that should refer to moz mobile connections before the variable is initialized. The patch assigned the reference by default and also removed a variable that is no longer used.

EJ, could you help review the patch? Thanks.
