0032442: Prevent sourceversion check in case of multi-server when doing requests on other server

Description

When doing datasource requests from WebPOS to the server the server will compute the sourceversion:
https://code.openbravo.com/erp/pmods/org.openbravo.mobile.core/file/b085729eb10c/src/org/openbravo/mobile/core/process/JSONProcessSimple.java#l62 [^]

When there are multiple servers it is possible that the store server has a different js version than the server. This can happen when updating the central server before the store server. As we only can support backward compatible changes this is not a problem by itself.

Therefore the source version check should only be done on the server from which the client side code is loaded.

Steps To Reproduce

1) install multiple servers
http://wiki.openbravo.com/wiki/Retail:Store_Server#Developer_Guide [^]

2) set all remote prefs
http://wiki.openbravo.com/wiki/Retail:Configuration_Guide#Remote_Data_Preferences [^]
3) set the central server to be the one which provides ticket loading
4) login to webpos
5) query for tickets
6) check that the central server requests contain the sourceversion in the json

Proposed Solution

I think that we should compute the sourceversion less often in case of remote prefs. For example we can only compute it once for each session. That could be a change on the server side code in JSONProcessSimple.

On the client side in ob-datasource.js the context check is fine that should happen. However, sourceversion check ([1]) should only happen for the requests which are going to the same location from which the code was loaded.
