[Systeminfo] Added filtering of cellular network listeners calls

[Feature] When only single-property cellular network listener is registered,
  it should only react to changes of default (first) SIM card. Changes of others should be ignored.

[Verification] Code compiles without errors.
  Feature was checked in chrome console and changes of second sim are ignored.
  TCT passrate on web-tct_2.4_r41 is 100%.
