Changing the refapp to the next snapshot for the modules using refapp distro import

With this pom, I was able to install coreapps and emrapi from a clean maven repo (removed org/openmrs folder from my maven local repo). 

I was able to reprovision the refapp distro from scratch. All the modules were loaded, so I guess everything might be working. 

All repos from [using the refapp distro import](https://github.com/openmrs/openmrs-contrib-bamboo/blob/master/list-repos-using-refapp-import.txt) should be now pointing to a version that can be actually used from maven.
