Problem description
For phetsims/qa#1170, when the Signed ammeter preference is selected, and then a battery is flipped, only the ammeter attached to the battery will give negative values in CODAP even though all ammeters show a negative value in the sim.

Steps to reproduce

1. Create a circuit similar to the one in the screenshots
2. Check all the variables
3. Press Start Auto Collect
4. Press Stop Auto Collect after a few seconds

5. In Preferences, select Signed for Ammeter Readout
6. Flip the battery
7. Press Start Auto Collect -- only the ammeter next to the battery will have negative numbers in CODAP even though the sim shows all negative values

8. Flip the battery again -- the negative value column will switch to positive values while the other columns switch to negative values (sim only shows positive values)

@samreid - Please investigate this one ... I suspect the wrapper needs to listen to the same property that the current ammeter is listening too ... or it needs to be adjusted in some way to match.
