Updated git submodules

Project: appc master f06b023ebfa4ce22a58e6548b817264dbb6eea61

Code changes to fix Exception

Reverted changes to method name in Transaction.java
to getuId() as this caused incorrect attributes
to be added to the generated JSON. Added unit test
to ensure this works as expected in the future.
